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]

Collection Method:clinical testing

The c.548C>A (p.P183H) alteration is located in exon 7 (coding exon 7) of the SEC14L2 gene. This alteration results from a C to A substitution at nucleotide position 548, causing the proline (P) at amino acid position 183 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
