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]

The c.452A>G (p.K151R) alteration is located in exon 1 (coding exon 1) of the ADRB3 gene. This alteration results from a A to G substitution at nucleotide position 452, causing the lysine (K) at amino acid position 151 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The ADRB3 p.Lys151Arg variant was not identified in the literature nor was it identified in ClinVar, Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs200133226) and in control databases in 44 of 220800 chromosomes at a frequency of 0.000199 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Ashkenazi Jewish in 21 of 9228 chromosomes (freq: 0.002276), European (non-Finnish) in 17 of 95098 chromosomes (freq: 0.000179), Latino in 5 of 28626 chromosomes (freq: 0.000175) and Other in 1 of 6142 chromosomes (freq: 0.000163); it was not observed in the African, East Asian, European (Finnish) and South Asian populations. The variant occurs outside of the splicing consensus sequence however 2 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan) predict the gain of a 3' splice site at the variant location. However, this information is not predictive enough to assume pathogenicity. The p.Lys151 residue is conserved in mammals however computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
