Genes affected

CHODL (HGNC:17807): (chondrolectin) This gene encodes a type I membrane protein with a carbohydrate recognition domain characteristic of C-type lectins in its extracellular portion. In other proteins, this domain is involved in endocytosis of glycoproteins and exogenous sugar-bearing pathogens. This protein localizes predominantly to the perinuclear region. Several transcript variants encoding a few different isoforms have been found for this gene. [provided by RefSeq, Feb 2011]

The c.305G>A (p.G102E) alteration is located in exon 2 (coding exon 2) of the CHODL gene. This alteration results from a G to A substitution at nucleotide position 305, causing the glycine (G) at amino acid position 102 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
