Genes affected

NADSYN1 (HGNC:29832): (NAD synthetase 1) Nicotinamide adenine dinucleotide (NAD) is a coenzyme in metabolic redox reactions, a precursor for several cell signaling molecules, and a substrate for protein posttranslational modifications. NAD synthetase (EC 6.3.5.1) catalyzes the final step in the biosynthesis of NAD from nicotinic acid adenine dinucleotide (NaAD).[supplied by OMIM, Apr 2004]

Collection Method: clinical testing

The c.470C>A (p.P157H) alteration is located in exon 7 (coding exon 7) of the NADSYN1 gene. This alteration results from a C to A substitution at nucleotide position 470, causing the proline (P) at amino acid position 157 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
