Genes affected

CCT7 (HGNC:1622): (chaperonin containing TCP1 subunit 7) This gene encodes a molecular chaperone that is a member of the chaperonin containing TCP1 complex (CCT), also known as the TCP1 ring complex (TRiC). This complex consists of two identical stacked rings, each containing eight different proteins. Unfolded polypeptides enter the central cavity of the complex and are folded in an ATP-dependent manner. The complex folds various proteins, including actin and tubulin. Alternative splicing results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 5 and 6. [provided by RefSeq, Oct 2009]

The c.877C>G (p.L293V) alteration is located in exon 8 (coding exon 8) of the CCT7 gene. This alteration results from a C to G substitution at nucleotide position 877, causing the leucine (L) at amino acid position 293 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
