Invitae RCV000801806 SCV000941602 likely pathogenic Autosomal dominant childhood-onset proximal spinal muscular atrophy with contractures 2019-03-28 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has been observed to be de novo in an individual with clinical features of BICD2-related conditions (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces tyrosine with serine at codon 556 of the BICD2 protein (p.Tyr556Ser). The tyrosine residue is moderately conserved and there is a large physicochemical difference between tyrosine and serine.

The following ACMG criteria were applied in classifying this variant: PS2,PM2,PP3.
