Genes affected
CCT8 (HGNC:1623): (chaperonin containing TCP1 subunit 8) This gene encodes the theta subunit of the CCT chaperonin, which is abundant in the eukaryotic cytosol and may be involved in the transport and assembly of newly synthesized proteins. Alternative splicing results in multiple transcript variants of this gene. A pseudogene related to this gene is located on chromosome 1. [provided by RefSeq, Sep 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.1603C>T (p.P535S) alteration is located in exon 15 (coding exon 15) of the CCT8 gene. This alteration results from a C to T substitution at nucleotide position 1603, causing the proline (P) at amino acid position 535 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
