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]

Ambry Genetics

Apr 26, 2024

The c.308C>A (p.A103D) alteration is located in exon 3 (coding exon 3) of the HINT2 gene. This alteration results from a C to A substitution at nucleotide position 308, causing the alanine (A) at amino acid position 103 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
