Genes affected

TRIM55 (HGNC:14215): (tripartite motif containing 55) The protein encoded by this gene contains a RING zinc finger, a motif known to be involved in protein-protein interactions. This protein associates transiently with microtubules, myosin, and titin during muscle sarcomere assembly. It may act as a transient adaptor and plays a regulatory role in the assembly of sarcomeres. Four alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

Ambry Genetics

Aug 10, 2021

The c.391C>T (p.R131C) alteration is located in exon 3 (coding exon 3) of the TRIM55 gene. This alteration results from a C to T substitution at nucleotide position 391, causing the arginine (R) at amino acid position 131 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
