Abstract
INTRODUCTION Liddle syndrome (LS), an autosomal dominant and inherited monogenic hypertension syndrome caused by pathogenic mutations in the epithelial sodium channel (ENaC) genes SCNN1A, SCNN1B, and SCNN1G. OBJECTIVE This study was designed to identify a novel SCNN1B missense mutation in a Chinese family with a history of stroke, and to confirm that the identified mutation is responsible for LS in this family. METHODS DNA samples were collected from the proband and 11 additional relatives. Next-generation sequencing was performed in the proband to find candidate variants. In order to exclude genetic polymorphism, the candidate variantin SCNN1B was verified in other family members, 100 hypertensives, and 100 healthy controls by Sanger sequencing. RESULTS Genetic testing revealeda novel and rare heterozygous variant in SCNN1B in the proband. This variant resulted in a substitution of threonine instead of proline at codon 617, altering the PY motif of β-ENaC. The identified mutation was only verified in 5 relatives. In silico analyses indicated that this variant was highly pathogenic. In this family, phenotypic heterogeneity was present among 6 LS patients. Tailored medicine with amiloride was effective in controlling hypertension and improving the serum potassium concentration in patients with LS. CONCLUSIONS We identified a novel SCNN1B mutation (c.1849C>A) in a family affected by LS. Patients with LS, especially those with severe hypertension, should be alert for the occurrence of premature stroke. Timely diagnosis using genetic testing and tailored treatment with amiloride can help LS patients to avoid severe complications.

Three Reportedly Unrelated Families With Liddle Syndrome Inherited From a Common Ancestor. Hypertension 2017; 71:273-279.

Abstract
Liddle syndrome is considered a rare Mendelian hypertension. We have previously described 3 reportedly unrelated families, native of an Italian area around the Strait of Messina, carrying the same mutation (βP617L) of the epithelial sodium channel. The aims of our study were (1) to evaluate whether a close genomic relationship exists between the 3 families through the analysis of mitochondrial DNA and Y chromosome; and (2) to quantify the genomic relatedness between the patients with Liddle syndrome belonging to the 3 families and assess the hypothesis of a mutation shared through identity by descent. HVRI (the hypervariable region I) of the mitochondrial DNA genome and the Y chromosome short tandem repeats profiles were analyzed in individuals of the 3 families. Genotyping 542 585 genome-wide single nucleotide polymorphisms was performed in all the patients with Liddle syndrome of the 3 families and some of their relatives. A panel of 780 healthy Italian adult samples typed for the same set of markers was used as controls. espite different lineages between the 3 families based on the analysis of mitochondrial DNA and Y chromosome, the 3 probands and their 6 affected relatives share the same ≈5 Mbp long haplotype which encompasses the mutant allele. Using an approach based on coalescent theory, we estimate that the 3 families inherited the mutant allele from a common ancestor ≈13 generations ago and that such an ancestor may have left ≈20 carriers alive today. The prevalence of Liddle syndrome in the region of origin of the 3 families may be much higher than that estimated worldwide.

Abstract
The amiloride-sensitive sodium channel beta subunit (SCNN1B) gene encodes the beta subunit of the epithelial sodium channel, which is involved in blood pressure homeostasis. The aim of the present study was to investigate the association between SCNN1B gene promoter methylation and essential hypertension (EH), and to explore whether SCNN1B methylation was altered by antihypertensive therapy. The present study recruited 282 individuals: 94 controls, 94 incident cases and 94 prevalent cases. Subsequently, the methylation status of six CpG sites in the SCNN1B promoter region was measured using bisulfite pyrosequencing technology. Among the six CpG sites, a significant difference in CpG1 and CpG2 methylation levels were detected between controls and incident cases (CpG1: β‑standardized=0.17, adjusted P=0.015; CpG2: β‑standardized=‑0.41, adjusted P=0.001). In addition, a significant difference was detected in CpG1 methylation levels between incident cases and prevalent cases (β‑standardized=‑0.252, adjusted P=3.77E‑04). The present study also demonstrated that CpG1 and CpG2 methylation levels were significantly lower in males compared with in females (CpG1: t=‑3.180, P=0.002; CpG2: t=‑2.148, P=0.033). CpG1 methylation was also shown to be positively correlated with age (controls: r=0.285, P=0.008; incident cases: r=0.401, P=0.0001; prevalent cases: r=0.367, P=0.001). These results indicated a significant association between EH and SCNN1B methylation, which was affected by age, gender and antihypertensive therapy.
