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

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.67).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.422 is higher than 0.05.
