Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_031438.4(NUDT12):c.968C>T(p.Pro323Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000046 in 1,305,118 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P323A) has been classified as Uncertain significance.

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]

Collection Method:clinical testing

The c.968C>T (p.P323L) alteration is located in exon 5 (coding exon 4) of the NUDT12 gene. This alteration results from a C to T substitution at nucleotide position 968, causing the proline (P) at amino acid position 323 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
