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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.524C>T (p.P175L) alteration is located in exon 6 (coding exon 5) of the TMOD3 gene. This alteration results from a C to T substitution at nucleotide position 524, causing the proline (P) at amino acid position 175 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
