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

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Orphanet, G2P, Ambry Genetics, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

• PM1: In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 8 uncertain in NM_005340.7
• 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.
• PP5: Variant 5-131159539-C-T is Pathogenic according to our data. Variant chr5-131159539-C-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 545660.Status of the report is criteria_provided_single_submitter, 1 stars.
