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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.311C>T (p.T104I) alteration is located in exon 4 (coding exon 3) of the GNPDA1 gene. This alteration results from a C to T substitution at nucleotide position 311, causing the threonine (T) at amino acid position 104 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
