Oculodentodigital Dysplasia Presenting as Spastic Paraparesis: The First Genetically Confirmed Korean Case and a Literature Review.

ABSTRACT: Oculodentodigital dysplasia (ODDD) is a rare autosomal dominant inherited disease caused by mutations of the human gap junction alpha 1 gene, which encodes the protein Connexin-43. Patients with ODDD may present with neurological deficits with a typical pleiotropic combination of characteristic craniofacial, ophthalmological, phalangeal, and dental anomalies. In this report, we describe the first genetically confirmed Korean ODDD patient, who presented with spastic paraparesis. We will also review the neurological aspects of ODDD as reported in the literature.

Hereditary Spastic Paraparesis

Project description:The goal of this project is to study differentially expressed genes in patients affected by Hereditary Spastic Paraplegia (HSP) linked to mutations of the gene encoding spastin an ubiquitously expressed protein that has recently been shown to be involved in microtubule regulation and vesicle trafficking by cell culture studies. Gene profiling was done with Affymetrix U95Av2 GeneChips using the total RNA extracted from muscle biopsies of 3 SPG4-linked HSP patients. Keywords: other

X-linked adrenoleukodystrophy presenting as autosomal dominant pure hereditary spastic paraparesis.

Project description:We present a family in which an initial clinical diagnosis of autosomal dominant pure hereditary spastic paraparesis (HSP) was made on the basis of a three generation pedigree in which both males and females presented with a spastic paraparesis. Subsequent biochemical and genetic analysis revealed that the family was in fact affected by the adrenomyeloneuropathy subtype of X-linked adrenoleukodystrophy. In the family described, both males and females were affected by a spastic paraparesis, and there was no male to male transmission, consistent with both autosomal dominant and X-linked inheritance. This report illustrates the importance of assaying very long chain fatty acids (VLCFAs) in any HSP family where there is no male to male transmission.

Intramedullary enterogenous cyst presenting with spastic paraparesis during two consecutive pregnancies: a case report.

Project description:A 35 year old woman presented with two episodes of spastic paraparesis, occurring in the third trimester of two consecutive pregnancies. The neurological symptoms seemed to be caused by an intramedullary cyst in the thoracic spinal cord. The cyst was subtotally removed and histopathologically diagnosed as enterogenous cyst. Other congenital abnormalities were absent. The peculiar timing of the clinical manifestation of an intramedullary cyst has not been described before. An unequivocal explanation for this phenomenon is missing, but several factors related to pregnancy that may play a part are discussed.

The first Korean case of Camurati-Engelmann disease (progressive diaphyseal dysplasia) confirmed by TGFB1 gene mutation analysis.

Project description:Camurati-Engelmann disease (CED) is an autosomal dominant progressive diaphyseal dysplasia caused by mutations in the transforming growth factor-beta1 (TGFB1) gene. We report the first Korean family with an affected mother and son who were diagnosed with CED. The proband is a 19-yr-old male with a history of abnormal gait since the age of 2. He also suffered from proximal muscle weakness, pain in the extremities, and easy fatigability. Skeletal radiographs of the long bones revealed cortical, periosteal, and endosteal thickenings, predominantly affecting the diaphyses of the upper and lower extremities. No other bony abnormalities were noted in the skull and spine and no remarkable findings were seen on laboratory tests. The patient's mother had a long-standing history of mild limb pain. Under the impression of CED on radiographic studies, we performed mutation analysis. A heterozygous G to A transition at cDNA position +653 in exon 4 of the TGFB1 gene (R218H) was detected in the patient and his mother.

Relative anterior microphthalmos in oculodentodigital dysplasia.

Project description:Here, we report a patient with oculodentodigital dysplasia (ODDD) caused by the c. 413G>A, p.Gly138Asp mutation in the gap junction protein alpha-1 gene. The patient suffered from characteristic dysmorphic features of ODDD. Ophthalmological investigation disclosed microcornea and a shallow anterior chamber, as expected. Surprisingly, the patient had a normal axial length and moderate myopia on both eyes. To the best of our knowledge, this is the first report on ODDD associated with relative anterior microphthalmos and myopia.

Two novel GJA1 variants in oculodentodigital dysplasia.

Project description:BackgroundOculodentodigital dysplasia (ODDD) is a rare disorder with pleiotropic effects involving multiple body systems, caused by mutations in the gap junction protein alpha 1 (GJA1) gene. GJA1 gene encodes a polytopic connexin membrane protein, Cx43, that is a component of connexon membrane channels.MethodsWe describe two unrelated female probands referred for a genetic review in view of a dysmorphic clinical phenotype.ResultsTwo novel missense mutations in GJA1 that substitute conserved amino acids in the first and second transmembrane domains (NM_000165.5: c.77T>C p.Leu26Pro and NM_000165.5:c.287T>G p.Val96Gly) were detected through targeted sequencing of GJA1. These variants were detected in the heterozygous state in the two Maltese probands and segregated with the disease phenotype.ConclusionThis report further expands the mutational spectrum of ODDD.

Gait Patterns in Patients with Hereditary Spastic Paraparesis.

Project description:BackgroundSpastic gait is a key feature in patients with hereditary spastic paraparesis, but the gait characterization and the relationship between the gait impairment and clinical characteristics have not been investigated.ObjectivesTo describe the gait patterns in hereditary spastic paraparesis and to identify subgroups of patients according to specific kinematic features of walking.MethodsWe evaluated fifty patients by computerized gait analysis and compared them to healthy participants. We computed time-distance parameters of walking and the range of angular motion at hip, knee, and ankle joints, and at the trunk and pelvis. Lower limb joint moments and muscle co-activation values were also evaluated.ResultsWe identified three distinct subgroups of patients based on the range of motion values. Subgroup one was characterized by reduced hip, knee, and ankle joint range of motion. These patients were the most severely affected from a clinical standpoint, had the highest spasticity, and walked at the slowest speed. Subgroup three was characterized by an increased hip joint range of motion, but knee and ankle joint range of motion values close to control values. These patients were the most mildly affected and had the highest walking speed. Finally, subgroup two showed reduced knee and ankle joint range of motion, and hip range of motion values close to control values. Disease severity and gait speed in subgroup two were between those of subgroups one and three.ConclusionsWe identified three distinctive gait patterns in patients with hereditary spastic paraparesis that correlated robustly with clinical data. Distinguishing specific features in the gait patterns of these patients may help tailor pharmacological and rehabilitative treatments and may help evaluate therapeutic effects over time.

Two Korean infants with genetically confirmed congenital nephrotic syndrome of Finnish type.

Project description:Congenital nephrotic syndrome is defined as nephrotic syndrome which manifests in utero or during the first 3 months of life. The prototype of congenital nephrotic syndrome is congenital nephrotic syndrome of Finnish type (CNF, OMIM #602716), which is caused by loss-of-function mutations of the nephrin gene (NPHS1). There have been few clinical case reports of CNF in Korea, but none of which was confirmed by genetic study. Here, we report two children with congenital nephrotic syndrome. Genetic analysis of the NPHS1 gene revealed compound heterozygous frame-shifting mutations (c.2156_2163 delTGCACTGC causing p.L719DfsX4 and c.3250_3251insG causing p.V1084GfsX12) in one patient and a missense mutation (c.1381G>A causing p.R460Q) and a nonsense mutation (c.2442C>G causing p.Y814X) in the other patient. The nonsense mutation was novel. The clinical courses of the patients were typical of CNF. This is the first report of genetically confirmed CNF in Korea to date. The early genetic diagnosis of CNF is important for proper clinical management of the patients and precise genetic counseling of the families.
