Genes affected

TMOD2 (HGNC:11872): (tropomodulin 2) This gene encodes a neuronal-specific member of the tropomodulin family of actin-regulatory proteins. The encoded protein caps the pointed end of actin filaments preventing both elongation and depolymerization. The capping activity of this protein is dependent on its association with tropomyosin. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Dec 2008]

May 05, 2023

The c.730A>G (p.I244V) alteration is located in exon 7 (coding exon 6) of the TMOD2 gene. This alteration results from a A to G substitution at nucleotide position 730, causing the isoleucine (I) at amino acid position 244 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
