Amyotrophic lateral sclerosis type 4 Uncertain:1
Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3C. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with spinocerebellar ataxia with axonal neuropathy 2 (MIM#606002). The mechanism for juvenile amyotrophic lateral sclerosis 4 (MIM#602433) has not been established, but both gain of function and dominant negative mechanisms have been speculated. Missense variants have been reported in patients with both conditions (OMIM, PMID: 23129421, 16644229, 30052327). (I) 0108 - This gene is associated with both recessive and dominant disease (OMIM). (I) 0115 - Variants in this gene are known to have variable expressivity. Variable severity and features, as well as age of onset have been reported (GeneReviews, PMID: 22088787). (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to leucine. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD <0.01 (1 heterozygote, 0 homozygotes). (SP) 0309 - An multiple alternative amino acid changes at the same position have been observed in gnomAD (v2: 64 heterozygotes, 0 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0708 - Other missense variants comparable to the one identified in this case have conflicting previous evidence for pathogenicity. The p.(Arg1846His) has been classified as a VUS in ClinVar and reported in an individual with ALS (PMID:25299611), while the p.(Arg1846Cys) variant has been classified as likely benign and benign in ClinVar. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1205 - This variant has been shown to be maternally inherited (by segregation analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
