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]

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP3: Nonframeshift variant in repetitive region in NM_023018.5
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0585 is higher than 0.05.
