Neuberg Centre For Genomic Medicine, NCGM RCV001823647 SCV002073246 uncertain significance Cerebellar ataxia, intellectual disability, and dysequilibrium syndrome 4 criteria provided, single submitter clinical testing The missense variant p.A772P in ATP8A2 (NM_016529.6) has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.A772P variant is observed in 1/30,530 (0.0033%) alleles from individuals of South Asian background in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. There is a small physicochemical difference between alanine and proline, which is not likely to impact secondary protein structure as these residues share similar properties. The p.A772P missense variant is predicted to be damaging by both SIFT and PolyPhen2. The alanine residue at codon 772 of ATP8A2 is conserved in all mammalian species. The nucleotide c.2314 in ATP8A2 is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance.
