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 27, 2024

The c.31G>T (p.V11F) alteration is located in exon 1 (coding exon 1) of the GALK2 gene. This alteration results from a G to T substitution at nucleotide position 31, causing the valine (V) at amino acid position 11 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
