A novel factor X gene mutation Val (GTC) 384Ala (GCC) in a Chinese family resulting in congenital factor X deficiency.

ABSTRACT: FX is a vitamin K-dependent coagulation protease critically essential for the coagulation cascade. FXD (congenital deficiency of factor X) is a rare coagulation disorder that inherited as an autosomal recessive trait. Here we reported a patient with bleeding diathesis from infant. The proband with pseudotumor in cerebral articular and cavity were identified as encapsulated hematocele ultimately. FX sequence analysis revealed that the patient carried a novel homozygous missense mutation that resulted in the Val384Ala substitution. Further investigation of the novel mutation would deepen our understanding of the bleeding mechanism involved in FXD.

A novel FBN2 mutation in a Chinese family with congenital contractural arachnodactyly.

Project description:Congenital contractural arachnodactyly (CCA, OMIM: 121050) is an autosomal dominant condition that shares skeletal features with Marfan syndrome (MFS, OMIM: 154700), including contractures, arachnodactyly, dolichostenomelia, scoliosis, crumpled ears and pectus deformities but excluding the ocular and cardiovascular complications that characterize MFS. These two similar syndromes result from mutations in two genes belonging to the fibrillin family, FBN1 and FBN2, respectively. We successfully identified a novel FBN2 mutation (C1406R) in a Chinese family with CCA for over five generations. This mutation was detected in the patients of this family but not in the seven unaffected family members or 100 normal individuals. SIFT and PolyPhen analyses suggested that the mutation was pathogenic. We identified a missense mutation in the calcium binding-epidermal growth factor (cbEGF)-like domain. Our study extends the mutation spectrum of CCA and confirms a relationship between mutations in the FBN2 gene and the clinical findings of CCA.

A novel GPR143 duplication mutation in a Chinese family with X-linked congenital nystagmus.

Project description:PURPOSE: To elucidate the molecular genetic defect of X-linked congenital nystagmus in a Chinese family. METHODS: Genomic DNA was prepared from peripheral blood. We used allele-sharing analysis to identify the possible locus harboring the disease-causing gene. We screened for mutations in the G protein-coupled receptor 143 gene (GPR143) by direct sequencing of the polymerase chain reaction (PCR)-amplified exons. RESULTS: In analyzing the candidate gene, GPR143, in the linked region, a 19 base pair (bp) duplication mutation in exon 1 was detected after direct DNA sequence analysis, which cosegregated in all patients of this family and was present in obligate female carriers. CONCLUSIONS: The identified 19 bp duplication in GPR143 induces a frame-shift and a premature stop codon, resulting in a truncated protein of 105 residues. These results suggest that this novel mutation is associated with the congenital nystagmus observed in this Chinese family and further support that GPR143 mutations are the underlying pathogenesis of the molecular mechanism for congenital nystagmus.

A novel mutation in TRIOBP gene leading to congenital deafness in a Chinese family.

Project description:BACKGROUND:The autosomal recessive non-syndromic deafness DFNB28 is characterized by prelingual sensorineural hearing loss. The disease is related with mutations in TRIOBP (Trio- and F-actin-Binding Protein) gene, which has three transcripts referred to as TRIOBP-5, TRIOBP?-?4 and TRIOBP-1. Among them, TRIOBP-5/-?4 are expressed in the inner ears and crucial for maintaining the structure and function of the stereocilia. METHODS:The proband is a 26-year-old Chinese female. She and her younger brother have being suffered from severe deafness since birth, whereas her parents, who are cousins, have normal communication ability. Hearing impairment of the two siblings was determined by pure tone audiometry. Whole Exome Sequencing (WES) was performed on the genomic DNA of the proband and Sanger sequencing was conducted on the DNA samples of the four family members. RESULTS:Tests of pure tone hearing thresholds showed a severe to profound symmetric hearing loss for the proband and her younger brother. Moreover, a novel TRIOBP c.1342C?>?T (p.Arg448*) variant was identified by WES in the DNA sample of the proband and confirmed by Sanger sequencing in DNA of the family members. CONCLUSIONS:The TRIOBP c.1342C?>?T (p.Arg448*) variant is predicted to disrupt TRIOBP-5 and TRIOBP-4, which may lead to the congenital deafness. The results will broaden the spectrum of pathogenic variants in TRIOBP gene. The characteristics of deafness in the family imply that marriage between close relatives should be avoided.

A novel GJA8 mutation (p.I31T) causing autosomal dominant congenital cataract in a Chinese family.

Project description:PURPOSE: To identify the genetic defect associated with autosomal dominant congenital nuclear cataract in a Chinese family. METHODS: Family history and clinical data were recorded. The genomic DNA was extracted from peripheral blood leukocytes. All the members were genotyped with microsatellite markers at loci considered to be associated with cataracts. Two-point logarithm of odds (LOD) scores were calculated by using the Linkage software after genotyping. Mutations were detected by DNA sequence analysis of the candidate genes. Effects of amino acid changes on the structure and function of proteins were predicted by bioinformatics analysis. RESULTS: Evidence of a linkage was obtained at markers D1S514 (LOD score [Z]=3.48, recombination fraction [theta]=0.0) and D1S1595 (Z=2.49, theta=0.0). Haplotype analysis indicated that the cataract gene was close to these two markers. Sequencing of the connexin 50 (GJA8) gene revealed a T>C transition at nucleotide position c.92. This nucleotide change resulted in the substitution of highly conserved isoleucine by threonine at codon 31(I31T). This mutation co-segregated with all affected individuals and was not observed in unaffected or 110 normal unrelated individuals. Bioinformatics analysis showed that a highly conserved region was located at Ile31, and the mutation was predicted to affect the function and secondary structure of the GJA8 protein. CONCLUSION: A novel mutation in GJA8 was detected in a Chinese family with autosomal dominant congenital nuclear cataract, providing clear evidence of a relationship between the genotype and the corresponding cataract phenotype.

A novel CRYGD mutation (p.Trp43Arg) causing autosomal dominant congenital cataract in a Chinese family.

Project description:To identify the genetic defect associated with autosomal dominant congenital nuclear cataract in a Chinese family, molecular genetic investigation via haplotype analysis and direct sequencing were performed Sequencing of the CRYGD gene revealed a c.127T>C transition, which resulted in a substitution of a highly conserved tryptophan with arginine at codon 43 (p.Trp43Arg). This mutation co-segregated with all affected individuals and was not observed in either unaffected family members or in 200 normal unrelated individuals. Biophysical studies indicated that the p.Trp43Arg mutation resulted in significant tertiary structural changes. The mutant protein was much less stable than the wild-type protein, and was more prone to aggregate when subjected to environmental stresses such as heat and UV irradiation.

A novel mutation in MIP associated with congenital nuclear cataract in a Chinese family.

Project description:PURPOSE: To identify the underlying genetic defect in a Chinese family affected with autosomal dominant congenital nuclear cataract. METHODS: A four-generation Chinese family with inherited nuclear cataract phenotype was recruited. Detailed family history and clinical data were recorded. All reported nuclear cataract-related candidate genes were screened for causative mutations by direct DNA sequencing. Effects of amino acid changes on the structure and function of protein were predicted by bioinformatics analysis. RESULTS: All affected individuals in this family showed nuclear cataracts. Sequencing of the candidate genes revealed a heterozygous c.559C>T change in the coding region of the major intrinsic protein (MIP), which caused a substitution of highly conserved arginine by cysteine at codon 187 (p.R187C). This mutation co-segregated with all affected individuals and was not observed in unaffected family members or 110 ethnically matched controls. Bioinformatics analysis showed that the mutation was predicted to affect the function and secondary structure of MIP protein. CONCLUSIONS: This study identified a novel disease-causing mutation p.R187C in MIP in a Chinese cataract family, expanding the mutation spectrum of MIP causing congenital cataract.

A Novel Missense Mutation of GATA4 in a Chinese Family with Congenital Heart Disease.

Project description:BackgroundCongenital heart disease (CHD) is the most prevalent type of birth defect in human, with high morbidity in infant. Several genes essential for heart development have been identified. GATA4 is a pivotal transcription factor that can regulate the cardiac development. Many GATA4 mutations have been identified in patients with different types of CHD.AimsIn this study, the NKX2-5, HAND1 and GATA4 coding regions were sequenced in a family spanning three generations in which seven patients had CHD. Disease-causing potential variation in this family was evaluated by bioinformatics programs and the transcriptional activity of mutant protein was analyzed by the dual luciferase reporter assay.ResultsA novel GATA4 mutation, c.C931T (p.R311W), was identified and co-segregated with the affected patients in this family. The bioinformatics programs predicted this heterozygous mutation to be deleterious and the cross-species alignment of GATA4 sequences showed that the mutation occurred within a highly conserved amino acid. Even though it resided in the nuclear localization signal domain, the mutant protein didn't alter its intracellular distribution. Nevertheless, further luciferase reporter assay demonstrated that the p.R311W mutation reduced the ability of GATA4 to activate its downstream target gene.ConclusionsOur study identified a novel mutation in GATA4 that likely contributed to the CHD in this family. This finding expanded the spectrum of GATA4 mutations and underscored the pathogenic correlation between GATA4 mutations and CHD.

A novel PAX6 mutation in a large Chinese family with aniridia and congenital cataract.

Project description:PurposeTo identify the disease-causing gene in a four-generation Chinese family affected with autosomal dominant aniridia and cataract.MethodsAll patients underwent full ophthalmic examination. For mutation analysis, a partial coding region (exons 5-14) of paired box gene 6 (PAX6) was sequenced with DNA from the proband. Single-strand conformation polymorphism analysis for exon 5 of PAX6 was performed to demonstrate co-segregation of the PAX6 mutation with aniridia in all family members and the absence of the mutation in the normal controls.ResultsThe proband and other patients in the family were affected with aniridia accompanied with congenital cataract. A novel heterozygous PAX6 mutation in exon 5 (c.475_491del17, p.Arg38ProfsX12) was identified, which was predicted to generate a frameshift and create a premature termination codon. This mutation co-segregated with the affected individuals in the family and did not exist in unaffected family members and 100 unrelated normal controls.ConclusionsA novel deletion mutation in the PAX6 gene was identified in a Chinese family with aniridia and congenital cataract. Our study expands the mutation spectrum of PAX6.

A Novel Mutation in CPT1A Resulting in Hepatic CPT Deficiency.

Project description:The present work presents a "from gene defect to clinics" pathogenesis study of a patient with a hitherto unreported mutation in the CPT1A gene. In early childhood, the patient developed a life-threatening episode (hypoketotic hypoglycemia, liver cytolysis, and hepatomegaly) evocative of a mitochondrial fatty acid oxidation disorder, and presented deficient fibroblast carnitine palmitoyltransferase 1 (CPT1) activity and homozygosity for the c.1783 C > T nucleotide substitution on exon 15 of CPT1A (p.R595W mutant). While confirming CPT1A deficiency, whole blood de novo acylcarnitine synthesis and the levels of carnitine and its esters formally linked intracellular free-carnitine depletion to intracellular carnitine esterification. Sequence alignment and modeling of wild-type and p.*R595W CPT1A proteins indicated that the Arg595 targeted by the mutated codon is phylogenetically well conversed. It contributes to a hydrogen bond network with neighboring residues Cys304 and Met593 but does not participate in the catalysis and carnitine pocket. Its replacement by tryptophan induces steric hindrance with the side chain of Ile480 located in ?-helix 12, affecting protein architecture and function. This hindrance with Ile480 is also originally described with tryptophan 304 in the known mutant p.C304W CPT1A, suggesting that the mechanisms that invalidate CPT1A activity and underlie pathogenesis could be common in both the new (p.R595W) and previously described (p.C304W) mutants.

A novel MIP gene mutation associated with autosomal dominant congenital cataracts in a Chinese family.

Project description:BACKGROUND: The major intrinsic protein gene (MIP), also known as MIP26 or AQP0, is a member of the water-transporting aquaporin family, which plays a critical role in the maintenance of lifelong lens transparency. To date, several mutations in MIP (OMIM 154050) have been linked to hereditary cataracts in humans. However, more pathogenic mutations remain to be identified. In this study, we describe a four-generation Chinese family with a nonsense mutation in MIP associated with an autosomal dominant congenital cataract (ADCC), thus expanding the mutational spectrum of this gene. METHODS: A large four-generation Chinese family affected with typical Y-suture cataracts combined with punctuate cortical opacities and 100 ethnically matched controls were recruited. Genomic DNA was extracted from peripheral blood leukocytes to analyze congenital cataract-related candidate genes. Effects of the sequence change on the structure and function of proteins were predicted by bioinformatics analysis. RESULTS: Direct sequencing of MIP in all affected members revealed a heterozygous nucleotide exchange c.337C>T predicting an arginine to a stop codon exchange (p.R113X). The substitution co-segregated well in all the affected individuals in the family and was not found in unaffected members or in the 100 unrelated healthy controls. Bioinformatics analysis predicted that the mutation affects the secondary structure and function of the MIP protein. CONCLUSIONS: We identified a novel mutation of MIP (p.R113X) in a Chinese cataract family. This is the first nonsense mutation of MIP identified thus far. This novel mutation is also the first disease-causing mutation located in the loop C domain of MIP. The results add to the list of mutations of the MIP linked to cataracts.
