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]

SIB Swiss Institute of Bioinformatics

Mar 18, 2024

This variant is interpreted for childhood-onset cardiomyopathy, autosomal recessive. The following ACMG Tag(s) were applied: Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium (PM2); Multiple lines of computational evidence support a deleterious effect on the gene or gene product (PP3); Well-established functional studies show a deleterious effect (PS3-supporting). -
