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]

The c.521A>T (p.D174V) alteration is located in exon 4 (coding exon 4) of the TRIM55 gene. This alteration results from a A to T substitution at nucleotide position 521, causing the aspartic acid (D) at amino acid position 174 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
