Synemin-related skeletal and cardiac myopathies: an overview of pathogenic variants.

This review analyzes data concerning patients with cardiomyopathies or skeletal myopathies associated with a variation in the intermediate filament (IF) synemin gene (), also referred to as desmuslin (). Molecular studies demonstrate that synemin copolymerizes with desmin and vimentin IF and interacts with vinculin, α-actinin, α-dystrobrevin, dystrophin, talin, and zyxin. It has been found that synemin is an A-kinase-anchoring protein (AKAP) that anchors protein kinase A (PKA) and modulates the PKA-dependent phosphorylation of several cytoskeletal substrates such as desmin.

AUTS2 Syndrome in a 68-year-old female: Natural history and further delineation of the phenotype.

Here we summarize the clinical and molecular findings in a 68-year-old female with dysmorphic features, mild-to-moderate intellectual disability, and behavioral findings suggesting autism spectrum disorder. SNP array analysis demonstrated a 257 kb deletion comprising exon 6 of AUTS2. This clinical report provides the natural history in the eldest patient yet to be reported, and complements the existing evidence suggesting that disruption of the AUTS2 leads to a recently delineated neurodevelopmental phenotype with a wide spectrum, namely "AUTS2 Syndrome.

De novo complex intra chromosomal rearrangement after ICSI: characterisation by BACs micro array-CGH.

Background: In routine Assisted Reproductive Technology (ART) men with severe oligozoospermia or azoospermia should be informed about the risk of de novo congenital or chromosomal abnormalities in ICSI program. Also the benefits of preimplantation or prenatal genetic diagnosis practice need to be explained to the couple.

Methods: From a routine ICSI attempt, using ejaculated sperm from male with severe oligozoospermia and having normal karyotype, a 30 years old pregnant woman was referred to prenatal diagnosis in the 17th week for bichorionic biamniotic twin gestation.

Retrospective diagnosis of Pallister-Killian syndrome by CGH array.

Objective And Methods: We report a girl presenting with a polymalformation syndrome. Despite a normal karyotype on peripheral lymphocytes and the unavailability of cultured fibroblasts, a tetrasomy 12p was identified on pulmonary DNA extracted from a postmortem biopsy, by use of comparative genomic hybridization (CGH) and confirmed by CGH array. The clinical picture of our patient was consistent, but not specific of the diagnosis of Pallister-Killian syndrome.

De novo monosomy 9p24.3-pter and trisomy 17q24.3-qter characterised by microarray comparative genomic hybridisation in a fetus with an increased nuchal translucency.

Objectives: Increased nuchal translucency (NT) during the first trimester of pregnancy is a useful marker to detect chromosomal abnormalities. Here, we report a prenatal case with molecular cytogenetic characterisation of an abnormal derivative chromosome 9 identified through NT.

Methods: Amniocentesis was performed because of an increased NT (4.
