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]

HINT1 Gene-Disease associations (from GenCC):

• Charcot-Marie-Tooth disease

  Inheritance: AR Classification: DEFINITIVE Submitted by: ClinGen
• Gamstorp-Wohlfart syndrome

ACMG classification

Our verdict: Pathogenic. The variant received 10 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
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 10 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 0.44207 (below the threshold of 3.09). Trascript score misZ: 0.49961 (below the threshold of 3.09). GenCC associations: The gene is linked to Gamstorp-Wohlfart syndrome, Charcot-Marie-Tooth disease.
• 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 VariationId is 37316.Status of the report is no_assertion_criteria_provided, 0 stars.
