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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.751G>T (p.A251S) 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 751, causing the alanine (A) at amino acid position 251 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
