Genes affected
UGT8 (HGNC:12555): (UDP glycosyltransferase 8) The protein encoded by this gene belongs to the UDP-glycosyltransferase family. It catalyzes the transfer of galactose to ceramide, a key enzymatic step in the biosynthesis of galactocerebrosides, which are abundant sphingolipids of the myelin membrane of the central and peripheral nervous systems. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.76G>A (p.V26M) alteration is located in exon 2 (coding exon 1) of the UGT8 gene. This alteration results from a G to A substitution at nucleotide position 76, causing the valine (V) at amino acid position 26 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
