Genes affected

DSCAML1 (HGNC:14656): (DS cell adhesion molecule like 1) The protein encoded by this gene is a member of the Ig superfamily of cell adhesion molecules and is involved in neuronal differentiation. The encoded membrane-bound protein localizes to the cell surface, where it forms aggregates that repel neuronal processes of the same cell type. [provided by RefSeq, Sep 2016]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with DSCAML1-related conditions. This variant is present in population databases (rs199968404, gnomAD 0.01%). This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 2105 of the DSCAML1 protein (p.Ala2105Ser). -
