Genes affected
SH3TC2 (HGNC:29427): (SH3 domain and tetratricopeptide repeats 2) This gene encodes a protein with two N-terminal Src homology 3 (SH3) domains and 10 tetratricopeptide repeat (TPR) motifs, and is a member of a small gene family. The gene product has been proposed to be an adapter or docking molecule. Mutations in this gene result in autosomal recessive Charcot-Marie-Tooth disease type 4C, a childhood-onset neurodegenerative disease characterized by demyelination of motor and sensory neurons.

Likely benign, criteria provided, single submitter | clinical testing | ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories | Feb 22, 2018 | The c.3686A>T; p.Asp1229Val variant (rs146920285) has been reported in the heterozygous state, in the absence of any other detected pathogenic SH3TC2 variants, in two HMSN I patients (Lassuthova 2011) and one CMT2 patient; however, the variant did not segregate with disease in the CMT family (Hoyer 2014). This variant is listed in the genome Aggregation Database (gnomAD) with a non-Finnish European population frequency of 0.4% (identified on 510 out of 126,418 chromosomes), in the Saudi Human Genome Program with a frequency of 2.6% (identified on 102 out of 3,920 chromosomes; Abouelhoda 2016), and is classified as likely benign/uncertain significance in ClinVar (ID: 188089). Based on the available information, the p.Asp1229Val variant is likely to be benign. - |

Charcot-Marie-Tooth disease type 4C Uncertain:1Benign:1
Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Apr 27, 2017 | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. - |

Susceptibility to mononeuropathy of the median nerve, mild Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Feb 13, 2018 | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. - |
Inborn genetic diseases Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 22, 2021 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
SH3TC2-related disorder Benign:1
Likely benign, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Mar 16, 2020 | This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). - |
