Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1 PP2 PP5_Very_Strong

The NM_005340.7(HINT1):​c.110G>C​(p.Arg37Pro) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000222 in 1,613,686 control chromosomes in the GnomAD database, with no homozygous occurrence. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R37Q) has been classified as Uncertain significance.

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: Pathogenic. The variant received 11 ACMG points.

• PM1: In a chain Adenosine 5'-monophosphoramidase HINT1 (size 124) in uniprot entity HINT1_HUMAN there are 13 pathogenic changes around while only 1 benign (93%) in NM_005340.7
• 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 5-131165096-C-G is Pathogenic according to our data. Variant chr5-131165096-C-G is described in ClinVar as Pathogenic. ClinVar VariationId is 37312.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
