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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 29, 2024 | The c.773A>C (p.K258T) alteration is located in exon 8 (coding exon 8) of the GALK2 gene. This alteration results from a A to C substitution at nucleotide position 773, causing the lysine (K) at amino acid position 258 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
