Genes affected

TPM4 (HGNC:12013): (tropomyosin 4) This gene encodes a member of the tropomyosin family of actin-binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non-muscle cells. Tropomyosins are dimers of coiled-coil proteins that polymerize end-to-end along the major groove in most actin filaments. They provide stability to the filaments and regulate access of other actin-binding proteins. In muscle cells, they regulate muscle contraction by controlling the binding of myosin heads to the actin filament. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2009]

Ambry Genetics

Nov 22, 2022

The c.212T>A (p.L71Q) alteration is located in exon 2 (coding exon 2) of the TPM4 gene. This alteration results from a T to A substitution at nucleotide position 212, causing the leucine (L) at amino acid position 71 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
