Genes affected

GALK2 (HGNC:4119): (galactokinase 2) This gene encodes a highly efficient N-acetylgalactosamine (GalNAc) kinase, which has galactokinase activity when galactose is present at high concentrations. The encoded protein is a member of the GHMP kinase family. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2017]

Ambry Genetics

Feb 06, 2023

The c.73A>G (p.M25V) alteration is located in exon 2 (coding exon 2) of the GALK2 gene. This alteration results from a A to G substitution at nucleotide position 73, causing the methionine (M) at amino acid position 25 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
