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.550A>G (p.T184A) alteration is located in exon 6 (coding exon 5) of the TMOD3 gene. This alteration results from a A to G substitution at nucleotide position 550, causing the threonine (T) at amino acid position 184 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
