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.

Charcot-Marie-Tooth disease type 4 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 17, 2023 | This sequence change creates a premature translational stop signal (p.Gln660*) in the SH3TC2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SH3TC2 are known to be pathogenic (PMID: 20220177, 27068304). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with clinical features of Charcot-Marie-Tooth disease (Invitae). ClinVar contains an entry for this variant (Variation ID: 543354). For these reasons, this variant has been classified as Pathogenic. - |
