Genes affected

RGL2 (HGNC:9769): (ral guanine nucleotide dissociation stimulator like 2) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of catalytic activity and small GTPase mediated signal transduction. Predicted to act upstream of or within negative regulation of cardiac muscle cell apoptotic process; positive regulation of phosphatidylinositol 3-kinase signaling; and regulation of Ral protein signal transduction. Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

PFDN6 (HGNC:4926): (prefoldin subunit 6) PFDN6 is a subunit of the heteromeric prefoldin complex that chaperones nascent actin (see MIM 102560) and alpha- and beta-tubulin (see MIM 602529 and MIM 191130, respectively) chains pending their transfer to the cytosolic chaperonin containing TCP1 (MIM 186980) (CCT) complex (Hansen et al., 1999 [PubMed 10209023]).[supplied by OMIM, Jul 2010]

ACMG classification

Our verdict: Likely_benign. The variant received -5 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.61).
• BP7: Synonymous conserved (PhyloP=2.33 with no splicing effect.
