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.

The c.662C>T (p.A221V) alteration is located in exon 9 (coding exon 5) of the SEC14L1 gene. This alteration results from a C to T substitution at nucleotide position 662, causing the alanine (A) at amino acid position 221 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
