Neuberg Centre For Genomic Medicine, NCGM RCV000986880 SCV002072989 uncertain significance Severe myoclonic epilepsy in infancy criteria provided, single submitter clinical testing The missense variant p.D1443N in SCN1A (NM_001165963.4) has been submitted to ClinVar as Likely Pathogenic but no details are available for independent assesment.The variant is not reported in literature in affected individuals. The p.D1443N variant is novel (not in any individuals) in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The p.D1443N missense variant is predicted to be damaging by both SIFT and PolyPhen2. The aspartic acid residue at codon 1443 of SCN1A is conserved in all mammalian species. The nucleotide c.4327 in SCN1A is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
