Genes affected

GALM (HGNC:24063): (galactose mutarotase) This gene encodes an enzyme that catalyzes the epimerization of hexose sugars such as glucose and galactose. The encoded protein is expressed in the cytoplasm and has a preference for galactose. The encoded protein may be required for normal galactose metabolism by maintaining the equilibrium of alpha and beta anomers of galactose.[provided by RefSeq, Mar 2009]

Nov 17, 2022

The c.8C>T (p.S3L) alteration is located in exon 1 (coding exon 1) of the GALM gene. This alteration results from a C to T substitution at nucleotide position 8, causing the serine (S) at amino acid position 3 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
