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]

SEC14L2 links:

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]

The c.496C>G (p.P166A) alteration is located in exon 6 (coding exon 6) of the SEC14L2 gene. This alteration results from a C to G substitution at nucleotide position 496, causing the proline (P) at amino acid position 166 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
