Genes affected

HINT1 (HGNC:4912): (histidine triad nucleotide binding protein 1) This gene encodes a protein that hydrolyzes purine nucleotide phosphoramidates substrates, including AMP-morpholidate, AMP-N-alanine methyl ester, AMP-alpha-acetyl lysine methyl ester, and AMP-NH2. The encoded protein interacts with these substrates via a histidine triad motif. This gene is considered a tumor suppressor gene. In addition, mutations in this gene can cause autosomal recessive neuromyotonia and axonal neuropathy. There are several related pseudogenes on chromosome 7. Several transcript variants have been observed. [provided by RefSeq, Dec 2015]

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a mutagenesis_site No effect on affinity for 3-indolepropionic acyl-adenylate but a 13.8-fold increased affinity for tryptamine adenosine phosphoramidate monoester. (size 0) in uniprot entity HINT1_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.988
• PP5: Variant 5-131162636-T-C is Pathogenic according to our data. Variant chr5-131162636-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 37316.Status of the report is no_assertion_criteria_provided, 0 stars.
