Genes affected

ADRB1 (HGNC:285): (adrenoceptor beta 1) The adrenergic receptors (subtypes alpha 1, alpha 2, beta 1, and beta 2) are a prototypic family of guanine nucleotide binding regulatory protein-coupled receptors that mediate the physiological effects of the hormone epinephrine and the neurotransmitter norepinephrine. Beta-1 adrenoceptors are predominately located in the heart. Specific polymorphisms in this gene have been shown to affect the resting heart rate and can be involved in heart failure.

The c.469T>C (p.Y157H) alteration is located in exon 1 (coding exon 1) of the ADRB1 gene. This alteration results from a T to C substitution at nucleotide position 469, causing the tyrosine (Y) at amino acid position 157 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
