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)

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.14C>T (p.T5I) alteration is located in exon 2 (coding exon 1) of the GNB5 gene. This alteration results from a C to T substitution at nucleotide position 14, causing the threonine (T) at amino acid position 5 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
