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.

Uncertain significance, criteria provided, single submitterclinical testingAthena DiagnosticsDec 02, 2022Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is uninformative in assessment of its pathogenicity (http://gnomad.broadinstitute.org). Computational tools disagree on the variant's effect on normal protein function. -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 13, 2021The c.1607G>A (p.R536Q) alteration is located in exon 11 (coding exon 11) of the SH3TC2 gene. This alteration results from a G to A substitution at nucleotide position 1607, causing the arginine (R) at amino acid position 536 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
