Genes affected

TMOD3 (HGNC:11873): (tropomodulin 3) Enables cadherin binding activity involved in cell-cell adhesion. Predicted to be involved in actin filament organization; muscle contraction; and myofibril assembly. Predicted to act upstream of or within actin cytoskeleton organization; erythrocyte development; and positive regulation of mitotic cell cycle phase transition. Located in adherens junction.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.712C>T (p.R238W) alteration is located in exon 7 (coding exon 6) of the TMOD3 gene. This alteration results from a C to T substitution at nucleotide position 712, causing the arginine (R) at amino acid position 238 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
