Genes affected

ZNF830 (HGNC:28291): (zinc finger protein 830) Predicted to enable nucleic acid binding activity and zinc ion binding activity. Predicted to be involved in several processes, including DNA-dependent DNA replication; mitotic DNA integrity checkpoint signaling; and preantral ovarian follicle growth. Predicted to act upstream of or within several processes, including blastocyst growth; chromosome organization; and intestinal epithelial structure maintenance. Predicted to be located in nucleoplasm. Predicted to be part of spliceosomal complex. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

CCT6B (HGNC:1621): (chaperonin containing TCP1 subunit 6B) 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. [provided by RefSeq, Feb 2015]

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.052656353).
