Genes affected

SGSM2 (HGNC:29026): (small G protein signaling modulator 2) The protein encoded by this gene is a GTPase activator with activity towards RAB32 and RAB33B, which are regulators of membrane trafficking. The encoded protein inactivates RAB32 and can bind RAB9A-GTP, a protein required for RAB32 activation. [provided by RefSeq, Oct 2016]

SGSM2-AS1 (HGNC:56091): (SGSM2 antisense RNA 1)

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.12938175).
