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.

The c.685G>A (p.V229M) alteration is located in exon 7 (coding exon 6) of the TMOD3 gene. This alteration results from a G to A substitution at nucleotide position 685, causing the valine (V) at amino acid position 229 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
