Genes affected

SORT1 (HGNC:11186): (sortilin 1) This gene encodes a member of the VPS10-related sortilin family of proteins. The encoded preproprotein is proteolytically processed by furin to generate the mature receptor. This receptor plays a role in the trafficking of different proteins to either the cell surface, or subcellular compartments such as lysosomes and endosomes. Expression levels of this gene may influence the risk of myocardial infarction in human patients. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2015]

The c.1639A>C (p.I547L) alteration is located in exon 13 (coding exon 13) of the SORT1 gene. This alteration results from a A to C substitution at nucleotide position 1639, causing the isoleucine (I) at amino acid position 547 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
