Genes affected

CCT6A (HGNC:1620): (chaperonin containing TCP1 subunit 6A) The protein encoded by this gene is 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. Alternate transcriptional splice variants of this gene, encoding different isoforms, have been characterized. In addition, several pseudogenes of this gene have been located.

Jan 23, 2024

The c.1202C>G (p.A401G) alteration is located in exon 10 (coding exon 10) of the CCT6A gene. This alteration results from a C to G substitution at nucleotide position 1202, causing the alanine (A) at amino acid position 401 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
