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)

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.26A>G (p.N9S) alteration is located in exon 2 (coding exon 1) of the GNB5 gene. This alteration results from a A to G substitution at nucleotide position 26, causing the asparagine (N) at amino acid position 9 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
