Genes affected

CCT3 (HGNC:1616): (chaperonin containing TCP1 subunit 3) 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 have been characterized for this gene. In addition, a pseudogene of this gene has been found on chromosome 8. [provided by RefSeq, Aug 2010]

The c.592T>A (p.Y198N) alteration is located in exon 7 (coding exon 7) of the CCT3 gene. This alteration results from a T to A substitution at nucleotide position 592, causing the tyrosine (Y) at amino acid position 198 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
