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]
FAM227B (HGNC:26543): (family with sequence similarity 227 member B)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2023The c.1238C>T (p.P413L) alteration is located in exon 10 (coding exon 10) of the GALK2 gene. This alteration results from a C to T substitution at nucleotide position 1238, causing the proline (P) at amino acid position 413 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
