Genes affected

GMDS (HGNC:4369): (GDP-mannose 4,6-dehydratase) GDP-mannose 4,6-dehydratase (GMD; EC 4.2.1.47) catalyzes the conversion of GDP-mannose to GDP-4-keto-6-deoxymannose, the first step in the synthesis of GDP-fucose from GDP-mannose, using NADP+ as a cofactor. The second and third steps of the pathway are catalyzed by a single enzyme, GDP-keto-6-deoxymannose 3,5-epimerase, 4-reductase, designated FX in humans (MIM 137020).[supplied by OMIM, Aug 2009]

The c.1087G>A (p.V363M) alteration is located in exon 11 (coding exon 11) of the GMDS gene. This alteration results from a G to A substitution at nucleotide position 1087, causing the valine (V) at amino acid position 363 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
