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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2023The c.920T>C (p.M307T) alteration is located in exon 9 (coding exon 8) of the TMOD2 gene. This alteration results from a T to C substitution at nucleotide position 920, causing the methionine (M) at amino acid position 307 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
