Genes affected

GLTP (HGNC:24867): (glycolipid transfer protein) The protein encoded by this gene is similar to bovine and porcine proteins which accelerate transfer of certain glycosphingolipids and glyceroglycolipids between membranes. It is thought to be a cytoplasmic protein. [provided by RefSeq, Jul 2008]

Jan 31, 2022

The c.556A>G (p.N186D) alteration is located in exon 5 (coding exon 5) of the GLTP gene. This alteration results from a A to G substitution at nucleotide position 556, causing the asparagine (N) at amino acid position 186 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
