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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2021The c.77G>A (p.C26Y) alteration is located in exon 1 (coding exon 1) of the TRIM55 gene. This alteration results from a G to A substitution at nucleotide position 77, causing the cysteine (C) at amino acid position 26 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
