Characterization of a Novel HIV-1 Circulating Recombinant Form, CRF01_AE/B'/C (CRF96_cpx), in Yunnan, China.

Currently, complex HIV-1 recombinations among the B', C, and CRF01_AE genotypes have frequently arisen in Yunnan, China. A novel HIV-1 complex circulating recombinant form (CRF) consisting of B', C, and CRF01_AE (CRF96_cpx) was recently characterized from three epidemiologically unlinked individuals. Two strains of them were isolated from the injecting drug users in this study, the remaining one strain (JL.

Prevalence and Clinical Impact of Human Pegivirus-1 Infection in HIV-1-Infected Individuals in Yunnan, China.

Human Pegivirus-1 (HPgV-1) may have a beneficial impact on disease progression in human immunodeficiency virus-1 (HIV-1) infection. However, analysis of the genotypic diversity of HPgV-1 and its relevance to the progression of HIV-1 disease remains limited. A total of 1062 HIV-1-infected individuals were recruited in all sixteen prefectures of Yunnan province, China.

Identification of a Novel HIV Type 1 Circulating Recombinant Form (CRF86_BC) Among Heterosexuals in Yunnan, China.

In recent years, multiple circulating recombinant forms (CRFs) and unique recombinant forms of human immunodeficiency virus type 1 (HIV-1) have been described in Yunnan, China. Here, we identified a novel HIV-1 CRF (CRF86_BC) isolated from three heterosexuals with no obvious epidemiologic linkage in western Yunnan (Baoshan prefecture) in China. CRF86_BC had a subtype C backbone with four subtype B fragments inserted into the pol, vpr, vpu, env, and nef gene regions, respectively.

Identification of novel mutations including a double mutation in patients with inherited cardiomyopathy by a targeted sequencing approach using the Ion Torrent PGM system.

Inherited cardiomyopathy is the major cause of sudden cardiac death (SCD) and heart failure (HF). The disease is associated with extensive genetic heterogeneity; pathogenic mutations in cardiac sarcomere protein genes, cytoskeletal protein genes and nuclear envelope protein genes have been linked to its etiology. Early diagnosis is conducive to clinical monitoring and allows for presymptomatic interventions as needed.

Near-Full-Length Genome Sequences of a Novel HIV-1 Circulating Recombinant Form, CRF01_AE/B'/C (CRF78_cpx), in Yunnan, China.

We report a novel HIV circulating recombinant form (CRF78_cpx) composed mainly of CRF01_AE with inserts from subtypes B and C identified from three epidemiologically unlinked individuals in Yunnan province, China. Two of the subjects are heterosexual men and one is a male intravenous drug user. Sequencing and analyzing the near-full-length genome of these three isolates (YNTC88, YNTC19, and YNTC35) revealed identical recombination breakpoints in all three viruses, but considerable genetic diversity between them, across the genomes, indicating that this is not a newly created CRF, only newly detected.
