A naturally occurring variant of GIPR (E354Q) associated with an increased incidence of insulin resistance, type 2 diabetes, and cardiovascular disease in humans responds to GIP stimulation with an exaggerated downregulation from the plasma membrane and a delayed recovery of GIP sensitivity following cessation of GIP stimulation.
This perturbation in the desensitization-resensitization cycle of the GIPR variant, revealed in studies of cultured adipocytes, may contribute to the link of the E354Q variant to metabolic disease.
Subsequent exome sequencing of two affected first cousins revealed heterozygous mutation c.158G>A (p.Gly53Asp) in GNB4, encoding guanine-nucleotide-binding protein subunit beta-4 (Gβ4), to cosegregate with the CMT phenotype in the family.
We examined whether a functional variant of the ADRA1A gene (Cys to Arg at codon 347 in exon 2, Cys347Arg) may enhance treatment response through decreased stimulation of this α1A-adrenoceptor, since antagonists of this receptor show promise in reducing cocaine use.
Our findings indicate that the mutation of EDNRA at S420T site should be regard as a potential AIMAH causative variation in familial and sporadic affected patients.
Using whole exome sequencing and several variant prioritization strategies based on disease network analysis, we identified Endothelin receptor type A (EDNRA) Ser420Thr mutation as a causative mutation of AIMAH.
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.
The SNP rs17055869 near the alpha-1A-adrenoreceptor gene (ADRA1A) showed the strongest association with metabolic syndrome (odds ratio 1.7, CI 1.3-2.2; P = 0.00007, P = 0.000098 after permutation).
We identified three tumor specific missense mutations in RGSL1 (ex6 c.664 G>A (Val222Ile), ex13 c.2262 C>G (Asp754Glu), and ex13 c.2316 C>T (Ser772Leu) in three different breast cancer patients.

In Spanish patients, the alpha(1A)-AR SNP rs1383914 was associated with the presence of FM (P = 0.01), and the alpha(1A)-AR SNP rs1048101 was linked with FIQ disability (P = 0.02).

Mexican patients with the rs574584 GG genotype presented the highest FIQ score compared with Mexican patients with other genotypes (P = 0.01), and in Mexicans SNP rs574584 was associated with FIQ morning stiffness (P = 0.04) and with FIQ tiredness upon awakening (P = 0.02).
Results suggest a sex-specific relationship between GRK4 A142V and blood pressure response among African-American men with early hypertensive nephrosclerosis.
Next, the neuroblastoma cells were transfected with the wild type GRK2 or its dominant negative mutant GRK2-K220R and the inhibition on cAMP level was determined in naïve and agonist-pretreated cells.

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).
Here, we studied platelets from GATA1-deficient mice and from a male patient (S14) with a bleeding diathesis attributed to a single amino acid substitution (R216Q) in the N-terminal GATA1 zinc finger that alters binding to DNA.
To examine whether genetic variation of the GPR10 locus might be associated with phenotypes relevant to obesity and/or blood pressure, the most common noncoding (G-62A) and coding (C914T [P305L]) polymorphisms were typed in 1,084 U.K. Caucasians.
