Genes affected

ADRB3 (HGNC:288): (adrenoceptor beta 3) The protein encoded by this gene belongs to the family of beta adrenergic receptors, which mediate catecholamine-induced activation of adenylate cyclase through the action of G proteins. This receptor is located mainly in the adipose tissue and is involved in the regulation of lipolysis and thermogenesis. Obesity and bodyweight-related disorders are correlated with certain polymorphisms in three subtypes of beta-adrenoceptor, among them, the ADRB3 gene.[provided by RefSeq, Oct 2019]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.949C>G (p.L317V) alteration is located in exon 1 (coding exon 1) of the ADRB3 gene. This alteration results from a C to G substitution at nucleotide position 949, causing the leucine (L) at amino acid position 317 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
