Genes affected

HGS (HGNC:4897): (hepatocyte growth factor-regulated tyrosine kinase substrate) The protein encoded by this gene regulates endosomal sorting and plays a critical role in the recycling and degradation of membrane receptors. The encoded protein sorts monoubiquitinated membrane proteins into the multivesicular body, targeting these proteins for lysosome-dependent degradation. [provided by RefSeq, Dec 2010]

The c.724C>A (p.L242M) alteration is located in exon 9 (coding exon 9) of the HGS gene. This alteration results from a C to A substitution at nucleotide position 724, causing the leucine (L) at amino acid position 242 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
