Genes affected

C2CD5 (HGNC:29062): (C2 calcium dependent domain containing 5) Enables calcium ion binding activity and calcium-dependent phospholipid binding activity. Involved in cellular response to insulin stimulus; intracellular protein transmembrane transport; and positive regulation of transport. Located in several cellular components, including centriolar satellite; cytoplasmic vesicle membrane; and ruffle membrane. [provided by Alliance of Genome Resources, Apr 2022]

C2CD5-AS1 (HGNC:55961): (C2CD5 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.789 is higher than 0.05.
