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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DSCAML1. . Gene score misZ 3.15 (greater than the threshold 3.09). Trascript score misZ 4.5764 (greater than threshold 3.09). GenCC has associacion of gene with motor neuron disorder, retinal disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.15894598).

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 02, 2023In 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with DSCAML1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.001%). This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 2077 of the DSCAML1 protein (p.His2077Arg). -
