Genes affected

GPD1L (HGNC:28956): (glycerol-3-phosphate dehydrogenase 1 like) The protein encoded by this gene catalyzes the conversion of sn-glycerol 3-phosphate to glycerone phosphate. The encoded protein is found in the cytoplasm, associated with the plasma membrane, where it binds the sodium channel, voltage-gated, type V, alpha subunit (SCN5A). Defects in this gene are a cause of Brugada syndrome type 2 (BRS2) as well as sudden infant death syndrome (SIDS). [provided by RefSeq, Jul 2010]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BP6: Variant 3-32106665-C-G is Benign according to our data. Variant chr3-32106665-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 391851.Status of the report is criteria_provided_single_submitter, 1 stars.
