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.101A>G (p.K34R) alteration is located in exon 2 (coding exon 2) of the NADSYN1 gene. This alteration results from a A to G substitution at nucleotide position 101, causing the lysine (K) at amino acid position 34 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
