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]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 0 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-1.0).
• BP6: Variant 11-71463406-A-G is Benign according to our data. Variant chr11-71463406-A-G is described in ClinVar as Benign. ClinVar VariationId is 1321836.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.739 is higher than 0.05.
