Genes affected

NUDT12 (HGNC:18826): (nudix hydrolase 12) Nucleotides are involved in numerous biochemical reactions and pathways within the cell as substrates, cofactors, and effectors. Nudix hydrolases, such as NUDT12, regulate the concentrations of individual nucleotides and of nucleotide ratios in response to changing circumstances (Abdelraheim et al., 2003 [PubMed 12790796]).[supplied by OMIM, Mar 2008]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.112107575).

Collection Method: clinical testing

The c.823C>T (p.L275F) alteration is located in exon 4 (coding exon 3) of the NUDT12 gene. This alteration results from a C to T substitution at nucleotide position 823, causing the leucine (L) at amino acid position 275 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
