Constitutively activated GRK4 gene variants (R65L, A142V, and A486V), by themselves or by their interaction with other genes involved in blood pressure regulation, are associated with essential hypertension and/or salt-sensitive hypertension in several ethnic groups.
A genetic model based on GRK4 R65L, GRK4 A142V, and GRK4 A486V was 94.4% predictive of SS hypertension, whereas the single-locus model with only GRK4 A142V was 78.4% predictive, and a 2-locus model of GRK4 A142V and CYP11B2 C-344T was 77.8% predictive of low-renin hypertension.
The present study aimed to evaluate the distribution of melanocortin 1 receptor gene variants R151C, R160W, and D294H within the Russian population of Eastern Siberia and its association with melanoma development.

When expressed in rat pheochromocytoma cell line cells, the R151C, R160W and D294H MC1R variants associated with melanoma and impaired cAMP signalling mediated ERK activation and ERK-dependent, agonist-induced neurite outgrowth comparable with wild-type.

Additionally, we suggest that patients with AD of the <i>SSTR4</i> rs2567608 TT genotype may be more vulnerable to ACEs and at a higher risk of suicide attempt.
None of following characteristics: current age, gender, term and kind of labor, 13 categories of childhood trauma, diet, alcohol drinking severity, age at alcohol drinking initiation, age at onset of problem drinking, cigarette smoking, and <i>SSTR4</i> rs2567608 was a significant predictor for <i>SSTR4</i> promoter region methylation.
A novel V2R mutation, T273M, identified in a boy with partial nephrogenic diabetes insipidus (NDI), shows intracellular localization and partial defects similar to the two mutants we described previously (10).

We hypothesized that 3 nonsynonymous GRK4 single-nucleotide polymorphisms, R65L (rs2960306), A142V (rs1024323), and A486V (rs1801058), would be associated with blood pressure response to atenolol, but not hydrochlorothiazide, and would be associated with long-term cardiovascular outcomes (all-cause death, nonfatal myocardial infarction, nonfatal stroke) in participants treated with an atenolol-based versus verapamil-SR-based antihypertensive strategy.
Results suggest a sex-specific relationship between GRK4 A142V and blood pressure response among African-American men with early hypertensive nephrosclerosis.
In contrast, inheritance of the Val(60)Leu and Arg(163)Gln SNPs was associated with increased PUVA erythemal sensitivity (reduced MPD) 72 h following treatment in all patients (n = 111; Val(60)Leu chi(2) = 5.764, P = 0.016; Arg(163)Gln chi(2) = 5.469, P = 0.019) and in a subset of patients with psoriasis (n = 55; Val(60)Leu chi(2) = 4.534, P = 0.033; Arg(163)Gln chi(2) = 7.298, P = 0.007).
The R151C, R160W and D294H alleles, designated 'R', are strongly associated with the RHC phenotype and have been proposed to result in loss of function receptors due to impaired G-protein coupling.
By screening patients with severe early onset obesity for mutations within the melanocortin 4 receptor (MC4R) gene, we have identified a missense mutation (C271R) that occurs homozygous in two siblings with obesity.
