Genes affected
HINT2 (HGNC:18344): (histidine triad nucleotide binding protein 2) Histidine triad proteins, such as HINT2, are nucleotide hydrolases and transferases that act on the alpha-phosphate of ribonucleotides (Brenner, 2002 [PubMed 12119013]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2023The c.407A>G (p.N136S) alteration is located in exon 5 (coding exon 5) of the HINT2 gene. This alteration results from a A to G substitution at nucleotide position 407, causing the asparagine (N) at amino acid position 136 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
