Genes affected

GNB5 (HGNC:4401): (G protein subunit beta 5) Heterotrimeric guanine nucleotide-binding proteins (G proteins), which integrate signals between receptors and effector proteins, are composed of an alpha, a beta, and a gamma subunit. These subunits are encoded by families of related genes. This gene encodes a beta subunit. Beta subunits are important regulators of alpha subunits, as well as of certain signal transduction receptors and effectors. Alternatively spliced transcript variants encoding different isoforms exist. [provided by RefSeq, Jul 2008]

CERNA1 (HGNC:52664): (competing endogenous lncRNA 1 for miR-4707-5p and miR-4767)

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 15-52191368-A-G is Benign according to our data. Variant chr15-52191368-A-G is described in ClinVar as [Benign]. Clinvar id is 1244293.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.748 is higher than 0.05.
