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]

The c.2089T>C (p.Y697H) alteration is located in exon 17 (coding exon 16) of the RGL2 gene. This alteration results from a T to C substitution at nucleotide position 2089, causing the tyrosine (Y) at amino acid position 697 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
