Genes affected

SEC14L2 (HGNC:10699): (SEC14 like lipid binding 2) This gene encodes a cytosolic protein which belongs to a family of lipid-binding proteins including Sec14p, alpha-tocopherol transfer protein, and cellular retinol-binding protein. The encoded protein stimulates squalene monooxygenase which is a downstream enzyme in the cholesterol biosynthetic pathway. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Oct 2008]

RNF215 (HGNC:33434): (ring finger protein 215) Predicted to enable ubiquitin protein ligase activity. Predicted to be involved in Golgi to vacuole transport; protein targeting to vacuole; and ubiquitin-dependent protein catabolic process. Predicted to be integral component of membrane. Predicted to be part of Golgi transport complex. Predicted to be active in endosome; membrane; and trans-Golgi network. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.25).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.375 is higher than 0.05.
