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]

Dec 21, 2022

The c.1546G>A (p.V516I) alteration is located in exon 12 (coding exon 12) of the CCT7 gene. This alteration results from a G to A substitution at nucleotide position 1546, causing the valine (V) at amino acid position 516 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
