Genes affected

SEC14L1 (HGNC:10698): (SEC14 like lipid binding 1) The protein encoded by this gene belongs to the SEC14 cytosolic factor family. It has similarity to yeast SEC14 and to Japanese flying squid RALBP which suggests a possible role of the gene product in an intracellular transport system. Multiple alternatively spliced transcript variants have been found for this gene; some variants represent read-through transcripts that include exons from the upstream gene C17orf86.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.0534 is higher than 0.05.
