Genes affected

NADK (HGNC:29831): (NAD kinase) NADK catalyzes the transfer of a phosphate group from ATP to NAD to generate NADP, which in its reduced form acts as an electron donor for biosynthetic reactions (Lerner et al., 2001 [PubMed 11594753]).[supplied by OMIM, Mar 2008]

Collection Method:clinical testing

The c.1720G>A (p.V574I) alteration is located in exon 14 (coding exon 13) of the NADK gene. This alteration results from a G to A substitution at nucleotide position 1720, causing the valine (V) at amino acid position 574 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
