Genes affected

TMOD1 (HGNC:11871): (tropomodulin 1) This gene encodes a member of the tropomodulin family. The encoded protein is an actin-capping protein that regulates tropomyosin by binding to its N-terminus, inhibiting depolymerization and elongation of the pointed end of actin filaments and thereby influencing the structure of the erythrocyte membrane skeleton. Multiple transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Oct 2009]

The c.817G>A (p.V273I) alteration is located in exon 8 (coding exon 7) of the TMOD1 gene. This alteration results from a G to A substitution at nucleotide position 817, causing the valine (V) at amino acid position 273 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
