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 submitterclinical testingAmbry GeneticsFeb 12, 2024The c.640G>T (p.D214Y) alteration is located in exon 7 (coding exon 7) of the GALK2 gene. This alteration results from a G to T substitution at nucleotide position 640, causing the aspartic acid (D) at amino acid position 214 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
