Genes affected
PDXK (HGNC:8819): (pyridoxal kinase) The protein encoded by this gene phosphorylates vitamin B6, a step required for the conversion of vitamin B6 to pyridoxal-5-phosphate, an important cofactor in intermediary metabolism. The encoded protein is cytoplasmic and probably acts as a homodimer. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2021The c.289A>G (p.I97V) alteration is located in exon 4 (coding exon 4) of the PDXK gene. This alteration results from a A to G substitution at nucleotide position 289, causing the isoleucine (I) at amino acid position 97 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
