Neuberg Centre For Genomic Medicine, NCGM RCV003340989 SCV004047913 uncertain significance Hypomyelinating leukodystrophy 2 criteria provided, single submitter clinical testing The missense c.814T>C (p.Tyr272His) variant in GJC2 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The variant is observed in 0.0004% alleles in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The amino acid Tyr at position 272 is changed to a His changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Tyr272His in GJC2 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain significance.
