Genes affected

COLGALT1 (HGNC:26182): (collagen beta(1-O)galactosyltransferase 1) The protein encoded by this gene is one of two enzymes that transfers galactose moieties to hydroxylysine residues of collagen and mannose binding lectin. This gene is constitutively expressed and encodes a soluble protein that localizes to the endoplasmic reticulum. [provided by RefSeq, Dec 2015]

The c.169G>C (p.A57P) alteration is located in exon 1 (coding exon 1) of the COLGALT1 gene. This alteration results from a G to C substitution at nucleotide position 169, causing the alanine (A) at amino acid position 57 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
