Sensenbrenner Syndrome Presenting with Severe Anorexia, Failure to Thrive, Chronic Kidney Disease and Angel-Shaped Middle Phalanges in Two Siblings.

ABSTRACT: Sensenbrenner syndrome is a very rare autosomal recessive disorder caused by variants in genes involved in the functional development of primary cilia. Typical clinical manifestations include craniofacial and skeletal abnormalities, hence the alternative name cranioectodermal dysplasia. Chronic kidney disease due to progressive tubulointerstitial nephritis (nephronophthisis) has been described in these patients. The authors present 2siblings with severe anorexia, failure to thrive, chronic kidney disease, and angel-shaped middle phalanges. Two previously described variants p.(Leu641*) and p.(Asp841Val) were identified in the WDR35 gene which is most commonly affected in this condition. Analysis of all coding exons of the GDF5 gene was normal. This is the first report of Sensenbrenner syndrome presenting with severe anorexia and failure to thrive at early age. Angel-shaped middle phalanges in the absence of the GDF5 variant may represent an overlapping phenotypic manifestation of ciliopathy.

Clinical and radiographic delineation of Bent Bone Dysplasia-FGFR2 type or Bent Bone Dysplasia with Distinctive Clavicles and Angel-shaped Phalanges.

Project description:Bent Bone Dysplasia-FGFR2 type is a relatively recently described bent bone phenotype with diagnostic clinical, radiographic, and molecular characteristics. Here we report on 11 individuals, including the original four patients plus seven new individuals with three longer-term survivors. The prenatal phenotype included stillbirth, bending of the femora, and a high incidence of polyhydramnios, prematurity, and perinatal death in three of 11 patients in the series. The survivors presented with characteristic radiographic findings that were observed among those with lethality, including bent bones, distinctive (moustache-shaped) small clavicles, angel-shaped metacarpals and phalanges, poor mineralization of the calvarium, and craniosynostosis. Craniofacial abnormalities, hirsutism, hepatic abnormalities, and genitourinary abnormalities were noted as well. Longer-term survivors all needed ventilator support. Heterozygosity for mutations in the gene that encodes Fibroblast Growth Factor Receptor 2 (FGFR2) was identified in the nine individuals with available DNA. Description of these patients expands the prenatal and postnatal findings of Bent Bone Dysplasia-FGFR2 type and adds to the phenotypic spectrum among all FGFR2 disorders. © 2016 Wiley Periodicals, Inc.

Congenital sucrase-isomaltase deficiency presenting with failure to thrive, hypercalcemia, and nephrocalcinosis.

Project description:BACKGROUND:Disaccharide Intolerance Type I (Mendelian Interance in Man database: *222900) is a rare inborn error of metabolism resulting from mutation in sucrase-isomaltase (Enzyme Catalyzed 3.2.1.48). Usually, infants with SI deficiency come to attention because of chronic diarrhea and nutritional evidence of malabsorption. CASE PRESENTATION:We describe an atypical presentation of this disorder in a 10-month-old infant. In addition to chronic diarrhea, the child displayed severe and chronic hypercalcemia, the evaluation of which was negative. An apparently coincidental right orbital hemangioma was detected. Following identification of the SI deficiency, an appropriately sucrose-restricted, but normal calcium diet regimen was instituted which led to cessation of diarrhea, substantial weight gain, and resolution of hypercalcemia. CONCLUSIONS:This case illustrates that, similar to congenital lactase deficiency (Mendelian Interance in Man database: *223000, Alactasia, Hereditary Disaccharide Intolerance Type II), hypercalcemia may complicate neonatal Sucrase-Isomaltase deficiency. Hypercalcemia in the presence of chronic diarrhea should suggest disaccharide intolerance in young infants.

FAILURE TO THRIVE.

Project description:Failure to thrive is a commonly encountered problem in Paediatric practice. This essentially generic term refers to children whose attained weight or rate of weight gain is significantly below that of other children of similar age and same sex. Several defining criteria have been proposed and help to differentiate true failure to thrive from other conditions causing apparent growth failure. There are numerous organic causes of failure to thrive, but non-organic failure to thrive is also an important entity and is caused by social, psychological and environmental factors. The clinical features are those of malnutrition, signs of underlying organic cause and specific manifestations of environmental/psychosocial deprivation. Indiscriminate laboratory investigations are usually non-contributory and have no role in evaluation. Management requires a multidisciplinary approach and hospitalization has a specific role. Although nutritional rehabilitation is the cornerstone of therapy, treatment of underlying factors-medical, psychological, social and environmental-should receive equally important attention. Long term physical, developmental and behavioural sequelae are known to occur in children with failure to thrive.

Triploidy mosaicism (45,X/68,XX) in an infant presenting with failure to thrive.

Project description:Triploid mosaicism is a rare aneuploidy syndrome characterized by growth retardation, developmental delay, 3-4 syndactyly, microphthalmia, coloboma, cleft lip and/or palate, genitourinary anomalies, and facial or body asymmetry. In the present report, we describe a 3-month-old female presenting with failure to thrive, growth retardation, and developmental delay. A chromosomal microarray demonstrated monosomy X, but her atypical phenotype prompted further evaluation with a chromosome analysis, which demonstrated 45,X/68,XX mixoploidy. To our knowledge, this is the first report of a patient with this chromosome complement. Mosaicism in chromosomal aneuploidies is likely under-recognized and may obscure the clinical diagnosis. At a time when comparative genomic hybridization and genome sequencing are increasingly used as diagnostic tools, this report highlights the clinical utility of chromosome analysis when a molecular diagnosis is not consistent with the observed phenotype.

Severe Short Stature in Two Siblings as the Presenting Sign of ACP5 Deficiency.

Project description:ACP5 deficiency is known to cause spondyloenchondrodysplasia (SPENCD), which is characterized by various autoimmune and neurological symptoms in addition to short stature.Two siblings from a consanguineous Turkish family, a girl aged 13 years (P1) and a boy aged 8 years (P2), presented to their endocrinologist with progressive growth failure and severe short stature (-5 SDS). They had no comorbid conditions and, on physical examination, there were no signs of an overt skeletal dysplasia with normal appearance of extremities. Other than a low baseline IGF-1, extensive laboratory workup, including growth hormone stimulation and IGF-1 generation tests, was normal. Exome sequencing was performed.Exome sequencing identified the presence of a homozygous frameshift mutation (p.Ser258Trpfs*39) in ACP5 in both siblings, which was confirmed by Sanger sequencing. This specific mutation has previously been described in patients with SPENCD. Additional workup in the two siblings showed distinct features of skeletal dysplasia on X-rays consistent with SPENCD, but none of the common autoimmune or neurological abnormalities associated with this condition.Severe short stature can be the only presenting sign of ACP5 deficiency and the latter could therefore be considered as a rare cause in the differential diagnosis of severe, proportionate growth failure.

Failure to thrive in babies and toddlers.

Project description:Failure to thrive in a child is defined as 'lack of expected normal physical growth' or 'failure to gain weight'. Diagnosis requires repeated growth measurements over time using local, age-appropriate growth centile charts. Premature babies with appropriate growth velocity and children with 'catch-down' growth, constitutional growth delay or familial short stature show normal growth variants, and usually do not require further evaluation. In Singapore, the most common cause of failure to thrive in children is malnutrition secondary to psychosocial and caregiver factors. 'Picky eating' is common in the local setting and best managed with an authoritative feeding style from caregivers. Other causes are malabsorption and existing congenital or chronic medical conditions. Child neglect or abuse should always be ruled out. Iron deficiency is the most common complication. The family doctor plays a pivotal role in early detection, timely treatment, appropriate referrals and close monitoring of 'catch-up' growth in these children.

Karnofsky Performance Score-Failure to Thrive as a Frailty Proxy?

Project description:Among patients listed for kidney transplantation, the Karnofsky Performance Status (KPS) Scale has been used as a proxy for frailty and proposed as a predictor of long-term posttransplant outcomes. The KPS is required by the Organ Procurement and Transplantation Network for all transplants; however, the interrater reliability of KPS reporting in kidney transplant candidates has not been well investigated, and there is concern regarding limitations of using KPS that may influence transplant eligibility.MethodsWe performed an observational study using existing Scientific Registry of Transplant Recipients data from 2006 to 2020 to examine the variability, reliability, and trends in the KPS among patients on the kidney transplant waitlist.ResultsOur analysis included 8197 kidney transplant candidates with >1 KPS in a 3-mo period. We observed 2-7 scores per patient with an average score of 78.9 (SD = 12, 95% confidence interval, 78.8-79.1). We found substantial variability in KPS reporting, in which 27% of the patients had scores that varied widely with 20-80 points in difference. Interrater reliability in the 10-point scale was poor (30%). When using a condensed 4-category scale (disabled, requires assistance, capable of self-care, normal activity), 38% of patients experienced at least a 1-category shift in their score.ConclusionsThe lack of reliability in KPS reporting raises concerns when applying the KPS as a proxy for frailty and a metric to be considered when evaluating candidacy for kidney transplantation.

A syndrome of severe intellectual disability, hypotonia, failure to thrive, dysmorphism, and thinning of corpus callosum maps to chromosome 7q21.13-q21.3.

Project description:Six individuals of consanguineous Bedouin kindred presented at infancy with an autosomal recessive syndrome of severe global developmental delay, positive pyramidal signs, unique dysmorphism, skeletal abnormalities, and severe failure to thrive with normal birth weights. Patients had a profound intellectual disability and cognitive impairment with almost no acquired developmental milestones by 12 months. Early-onset axial hypotonia evolved with progressive muscle weakness, reduced muscle tone, and hyporeflexia. Craniofacial dysmorphism consisted of a triangular face with a prominent forehead and midface hypoplasia. Magnetic resonance imaging (MRI) demonstrated thinning of the corpus callosum and paucity of white matter. Genome-wide linkage analysis identified a single ~4 Mbp disease-associated locus on chromosome 7q21.13-q21.3 (LOD score>5). Whole-exome and genome sequencing identified no nonsynonymous pathogenic biallelic variants in any of the genes within this locus. Following the exclusion of partially resembling syndromes, we now describe a novel autosomal recessive syndrome mapped to a ~4Mbp locus on chromosome 7.

Rapid Weight Loss and Severe Failure to Thrive Mimicking Lipodystrophy Syndrome in a 1-Year-Old Taiwanese Girl with Costello Syndrome.

Project description:Costello syndrome (CS) is a type of RASopathy caused mainly by de-novo heterozygous pathogenic variants in the HRAS gene located on chromosome 11p15.5. The phenotype of CS is characterized by prenatal overgrowth, postnatal failure to thrive, curly or sparse fine hair, coarse facial features, and multisystem involvement, including cardiovascular, endocrine, and gastroenterological disorders. We present a one-year-old girl with rapid weight loss and severe failure to thrive. She had gastroesophageal reflux at the age of four months with subsequent rapid weight loss. The loss of fat tissue over the whole body, refractory to a hypercaloric diet, mimicked the presentation of progressive lipodystrophy and masked the dysmorphic features of CS. The final diagnosis of CS was made by whole exome sequencing, which demonstrated a hot-spot, heterozygouspathogenic variant in the HRAS gene (c.34G > A, rs104894229). Our patient illustrates that the excessive energy needs in CS patients may lead to severe failure to thrive and cause challenges in diagnosing CS. This case also highlights the importance of recognizing CS in patients with a history of prenatal overgrowth, polyhydramnios presenting with severe failure to thrive refractory to pharmacotherapy and tube feeding.

A Middle-Aged Man Presenting With Progressive Heart Failure, Myopathy, and Monoclonal Gammopathy of Uncertain Significance.

Project description:A 48-year-old man presented with rapidly progressive heart failure and monoclonal gammopathy of uncertain significance. No specific cause was detected on endomyocardial biopsy. As the heart failure worsened, he also developed progressive skeletal myopathy. This provided the clue to the diagnosis, and cardiac function recovered rapidly with cause-directed therapy. (Level of Difficulty: Intermediate.).
