Genes affected

GNPDA1 (HGNC:4417): (glucosamine-6-phosphate deaminase 1) Glucosamine-6-phosphate deaminase (EC 3.5.99.6) is an allosteric enzyme that catalyzes the reversible conversion of D-glucosamine-6-phosphate into D-fructose-6-phosphate and ammonium (Arreola et al., 2003 [PubMed 12965206]).[supplied by OMIM, Jan 2010]

The c.461T>A (p.V154E) alteration is located in exon 5 (coding exon 4) of the GNPDA1 gene. This alteration results from a T to A substitution at nucleotide position 461, causing the valine (V) at amino acid position 154 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
