Microdeletions in chromosome 17q22, where the NOG gene resides, have been reported leading to the NOG-related symphalangism spectrum disorder (NOG-SSD), intellectual disability and other developmental abnormalities. In this study we reported a dominant Chinese Han family segregating with typical NOG-SSD symptoms including proximal symphalangism, conductive hearing loss, amblyopia and strabismus...
Background. Aromatase inhibitors (AIs) can significantly improve semen parameters in infertile men. In this study, we investigated the efficacy of AIs for azoospermia a Chinese population with AZFc microdeletion. Aims. Patients microdeletion who were treated analyzed retrospectively by collecting clinical data, including their hormone profile and treatment outcome. divided into those sperm afte...
Autism is a childhood neurodevelopmental disorder with a strong genetic component, yet the identification of autism susceptibility loci remains elusive. We investigated 180 autism probands and 372 control subjects by array comparative genomic hybridization (aCGH) using a 19K whole-genome tiling path bacterial artificial chromosome microarray to identify submicroscopic chromosomal rearrangements...
Objective Prenatal ultrasound features, associated anomalies and genetic abnormalities of microtia cases were analyzed to explore the feasibility value prenatal for diagnosis microtia. Methods The ultrasonographic anomalies, chromosome examination results follow-up 81 fetuses with congenital retrospectively. Results Among diagnosed after birth, 2 missed on ultrasound, 1 case was as unilateral b...
AIM To draw up recommendations for the investigation and management of children with a microdeletion of chromosome 22q11. METHODS A retrospective review of case notes from patients with a chromosome 22q11 microdeletion identified by cytogenetics laboratories of the south and west of Britain over a four year period. RESULTS A total of 210 cases were identified. Age at diagnosis was 0-1 years...
INTRODUCTION Chromosomal aberrations of chromosome 16 are uncommon and submicroscopic deletions have rarely been reported. At present, a cytogenetic or molecular abnormality can only be detected in 55% of Rubinstein-Taybi syndrome patients, leaving the diagnosis in 45% of patients to rest on clinical features only. Interestingly, this microdeletion of 16 p13.3 was found in a young child with an...
INTRODUCTION Although assisted reproduction techniques are used extensively in Iran, screening for Y chromosome microdeletions before intracytoplasmic sperm injection is often undervalued. Our aim was to investigate Y chromosome microdeletions in men with idiopathic azoospermia or severe oligospermia. MATERIALS AND METHODS In 99 selected patients with azoospermia or severe oligospermia and el...
