Genes affected

NUDT3 (HGNC:8050): (nudix hydrolase 3) NUDT3 belongs to the MutT, or Nudix, protein family. Nudix proteins act as homeostatic checkpoints at important stages in nucleoside phosphate metabolic pathways, guarding against elevated levels of potentially dangerous intermediates, like 8-oxo-dGTP, which promotes AT-to-CG transversions (Safrany et al., 1998 [PubMed 9822604]).[supplied by OMIM, Feb 2011]

RPS10-NUDT3 (HGNC:49181): (RPS10-NUDT3 readthrough) This locus represents naturally occurring read-through transcription between the neighboring RPS10 (ribosomal protein S10) and NUDT3 (nudix (nucleoside diphosphate linked moiety X)-type motif 3) genes on chromosome 6. The read-through transcript produces a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Feb 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2573876).

Collection Method: clinical testing

The c.511A>T (p.I171F) alteration is located in exon 5 (coding exon 5) of the NUDT3 gene. This alteration results from a A to T substitution at nucleotide position 511, causing the isoleucine (I) at amino acid position 171 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
