Variants in ZZS Complex‐Associated Genes TEX11 and M1AP Are Responsible for Male Infertility and Nonobstructive Azoospermia

Andrology, EarlyView.
ABSTRACT Background Nonobstructive azoospermia (NOA) is the most severe form of male infertility, with genetic factors contributing to approximately 30% of cases. However, only a small fraction of all NOA cases can be explained by the current genetic findings.

Can Hormonal Therapy Improve the Outcomes of mTESE in Patients With Non‐Obstructive Azoospermia?

Andrology, EarlyView.
ABSTRACT Background Non‐obstructive azoospermia (NOA) represents the most severe form of male infertility. Hypogonadism is common in NOA patients, and normal testosterone (T) levels are considered essential for spermatogenesis. Fertility‐preserving hormonal therapy (FpHT) has been proposed to optimize hormonal milieu and improve sperm retrieval rates ...

Dystrophia Smolandiensis is characterized by a novel NQO1 variant and a distinct phenotype from COL17A1‐associated epithelial recurrent erosion dystrophy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the molecular cause of the two epithelial recurrent erosion dystrophies, Dystrophia Smolandiensis and Dystrophia Helsinglandica, and to identify phenotypic differences between the two conditions. Methods DNA samples and clinical data from structured interview records were obtained from the Swedish families in which ...

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

Acta Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

From a novel pathogenic SAMD9L variant to cohort‐wide insights: Whole‐genome sequencing highlights somatic genetic rescue and phenotypic heterogeneity

British Journal of Haematology, EarlyView.
Summary Germline gain‐of‐function variants in sterile alpha motif domain–containing 9‐like (SAMD9L), located on chromosome 7q, cause a multisystem disorder characterized by bone marrow failure, immunodeficiency and variable neurological involvement. Disease evolution is frequently shaped by somatic genetic rescue (SGR), most commonly through monosomy 7,
