Genes affected

SCAP (HGNC:30634): (SREBF chaperone) This gene encodes a protein with a sterol sensing domain (SSD) and seven WD domains. In the presence of cholesterol, this protein binds to sterol regulatory element binding proteins (SREBPs) and mediates their transport from the ER to the Golgi. The SREBPs are then proteolytically cleaved and regulate sterol biosynthesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

The c.3200C>T (p.A1067V) alteration is located in exon 20 (coding exon 19) of the SCAP gene. This alteration results from a C to T substitution at nucleotide position 3200, causing the alanine (A) at amino acid position 1067 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
