Disorders of sex development (DSD) represent a group of congenital conditions in which there is a discrepancy between the chromosomal and (or) gonadal sex and the structure of the genitals. Within the DSD there is a subgroup of 46,XX testicular DSD (46,XX TDSD), which may be caused by the translocation of the SRY gene, and more rarely - due to other causes (SRY-negative forms). In this report, we present an observation of a patient with SRY-negative 46,XX TDSD, in whom the condition was initially regarded as a virile form of congenital adrenal hyperplasia, then as idiopathic intrauterine virilization in a girl.

Whole exome sequencing (WES) is essential for identifying genetic variants linked to diseases. This study compares available to date four exome enrichment kits: Agilent SureSelect Human All Exon v8, Roche KAPA HyperExome, Vazyme VAHTS Target Capture Core Exome Panel, and Nanodigmbio NEXome Plus Panel v1. We evaluated target design, coverage statistics, and variant calling accuracy across these four different exome capture products.

Using BW25113 as a host, we isolated a novel lytic phage from the commercial poly-specific therapeutic phage cocktail Sextaphage (Microgen, Russia). We provide genetic and phenotypic characterization of the phage and describe its host range on the ECOR collection of reference strains. The phage, hereafter named Sxt1, is a close relative of classical coliphage T3 and belongs to the genus, yet its internal virion proteins, forming an ejectosome, differ from those of T3.

Auditory neuropathy spectrum disorder (ANSD) is often missed by standard hearing tests, accounting for up to 10% of hearing impairments (HI) and commonly linked to variants in 23 genes. We assessed 122 children with HI, including 102 with sensorineural hearing loss (SNHL) and 20 with ANSD. SNHL patients were genotyped for common variants using qPCR, while ANSD patients underwent whole exome sequencing, with variants analyzed across 249 genes.

Article Synopsis
  • * Genetic analysis using trio-based exome sequencing found benign variants of the AIRE gene in all participants, which helped differentiate AAI and exclude APS type 1.
  • * The study recommends whole genome analysis in future research to discover genetic predictors of autoimmune diseases, after identifying risk alleles in patients and noting the prevalence of specific haplotypes in healthy individuals.
