Leukodystrophy, hypomyelinating, 23, with ataxia, deafness, liver dysfunction, and dilated cardiomyopathy Pathogenic:3
Pathogenic, criteria provided, single submitter | clinical testing | Victorian Clinical Genetics Services, Murdoch Childrens Research Institute | Jul 17, 2023 | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with leukodystrophy, hypomyelinating, 23, with ataxia, deafness, liver dysfunction, and dilated cardiomyopathy (MIM#619688), where this may occur through the formation of cytoplasmic aggregates (PMID: 33964137). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to glutamine. (I) 0252 - This variant is homozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.01 for a recessive condition (5 heterozygotes, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v3) (2 heterozygotes, 0 homozygotes). (I) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0600 - Variant is located in the annotated RNF220 family domain (DECIPHER). (I) 0802 - This variant has moderate previous evidence of pathogenicity in unrelated individuals. This variant has been reported in a homozygous Chinese individual, in addition to four homozygous families from the Roma region with hypomyelination, hearing loss and ataxia. Three of these families were found to have common ancestry by haplotype analysis (PMID: 36083980, PMID: 33964137). (SP) 0901 - This variant has strong evidence for segregation with disease. This variant has been found to segregate extensively in multiple affected individuals within several families (PMID: 33964137). (SP) 1001 - This variant has strong functional evidence supporting abnormal protein function. Fibroblasts from affected individuals demonstrated protein mislocalization, and transfected cells showed impaired lamin B1 binding (PMID: 33964137). (SP) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign - |
