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]

The c.362A>T (p.H121L) alteration is located in exon 5 (coding exon 5) of the GALK2 gene. This alteration results from a A to T substitution at nucleotide position 362, causing the histidine (H) at amino acid position 121 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
