Genes affected
NUDT2 (HGNC:8049): (nudix hydrolase 2) This gene encodes a member of the MutT family of nucleotide pyrophosphatases, a subset of the larger NUDIX hydrolase family. The gene product possesses a modification of the MutT sequence motif found in certain nucleotide pyrophosphatases. The enzyme asymmetrically hydrolyzes Ap4A to yield AMP and ATP and is responsible for maintaining the intracellular level of the dinucleotide Ap4A, the function of which has yet to be established. This gene may be a candidate tumor suppressor gene. Alternative splicing has been observed at this locus and four transcript variants, all encoding the same protein, have been identified.

Intellectual developmental disorder with or without peripheral neuropathy Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingFoundation for Research in Genetics and Endocrinology, FRIGE's Institute of Human GeneticsDec 31, 2024A homozygous three base pair deletion (c.410_412del) in exon 5 of the NUDT2 gene that results in deletion of amino acid glutamic acid at codon 137 was detected (p.Glu137del). This variant has not been reported in the 1000 genomes and has a MAF of 0.0004% in the gnomAD database. The in-silico prediction of the variant is damaging MutationTaster2. The reference region is conserved across species. In summary, the variant meets our criteria to be classified as a variant of uncertain significance. -
