Variant Spectrum of Renal Ciliopathies in Turkish Cohort and Genotype-Phenotype Association Specifically in Autosomal Dominant Polycystic Kidney Disease.

Renal ciliopathies are a genetically and phenotypically heterogeneous group of diseases characterized by cystic and dysplastic kidneys. The aim of this study was to investigate the correlation between genetic changes that cause renal ciliopathies and phenotypic outcomes. The study group consisted of 137 patients diagnosed with renal ciliopathy disease.

Expanding the Genetic and Phenotypic Spectrum of Mowat-Wilson Syndrome: A Study of 10 Turkish Patients With an Intrafamilial Recurrence Caused by First Intragenic Large Deletion.

Mowat-Wilson syndrome (MWS) is a complex disorder caused by heterozygous ZEB2 gene variations creating haploinsufficiency. The main clinical features are evolving facial dysmorphism, intellectual disability, eye and brain malformations, and various organ anomalies. Our study examines 10 Turkish patients, who had clinical diagnosis, underwent evaluation, clinical investigations, and genetic tests in multiple tertiary centers across Türkiye, and were molecularly diagnosed with MWS.

A novel variant of the gene: nonclassical presentation from Turkey.

Objectives: Lipoid congenital adrenal hyperplasia (LCAH) is a rare autosomal recessive disease caused by mutations in the steroidogenic acute regulatory protein () gene, expressed in the adrenal and gonadal tissues. In classical LCAH, individuals with 46, XY chromosomes present with a female appearance of the external genitalia due to insufficient androgen production. In the non-classical form, a milder phenotype is observed with male external genitalia.

A Deeper Insight into , , and Variants and Genotype-Phenotype Correlation of a Turkish Cohort with Alport Syndrome.

Introduction: Alport syndrome (AS) is an inherited, rare, progressive kidney disease that affects the eye and ear physiology. Pathogenic variants of account for 85% of all cases, while and account for the remaining 15%.

Methods: Targeted next-generation sequencing of the , , and genes was performed in 125 Turkish patients with AS.

A Novel RNPC3 Gene Variant Expands the Phenotype in Patients with Congenital Hypopituitarism and Neuropathy.

Introduction: Pathogenic biallelic RNPC3 variants cause congenital hypopituitarism (CH) with congenital cataracts, neuropathy, developmental delay/intellectual disability, primary ovarian insufficiency, and pituitary hypoplasia. Here, we aimed to evaluate the clinical and molecular characteristics of 2 patients with CH and neuropathy.

Materials And Methods: Proband was evaluated by clinical, laboratory, and radiological exams, followed by exome sequencing (ES).

Clinical and genetic spectrum from a prototype of ciliopathy: Joubert syndrome.

Objective: Joubert syndrome is a neurodevelopmental disorder with a distinctive hindbrain malformation called molar tooth sign, causing motor and cognitive impairments. More than 40 genes have been associated with Joubert syndrome. We aim to describe a group of Joubert syndrome patients clinically and genetically emphasizing organ involvement.

Whole-Exome Sequencing (WES) results of 50 patients with chronic kidney diseases: a perspective of Alport syndrome.

Objective: Chronic kidney disease (CKD) remains one of the major common health problems, and the number of people affected by the disease is progressively increasing in Turkey and worldwide. This study aimed to investigate molecular defects in Alport syndrome (AS) and other genes in patients with clinically suspected CKD using whole-exome sequencing (WES).

Methods: Patients with clinical suspicion of CKD were included in the study.

Expanding the genotypic and phenotypic landscapes of rhizomelic chondrodysplasia punctata type 3 (RCDP3) with two novel families, and a review of the literature.

Rhizomelic chondrodysplasia punctata (RCDP) are a group of peroxisomal disorders caused by plasmalogen synthesis defects. Patients with RCDP present with rhizomelic short stature, characteristic punctate epiphyseal calcifications, congenital cataracts, severe intellectual disability, seizures, and facial dysmorphism. Pathogenic variants in AGPS result in RCDP type 3 (RCDP3) which is an extremely rare disorder characterized by isolated ADHAPS deficiency.

Phenotypic and molecular characterization of five patients with PIK3CA-related overgrowth spectrum (PROS).

Somatic and germline PI3K-AKT-mTOR pathway pathogenic variants are involved in several segmental overgrowth phenotypes such as the PIK3CA-related overgrowth spectrum (PROS), Proteus syndrome, and PTEN hamartoma tumor syndrome. In this study, we describe five patients with PROS. We identified by high-throughput sequencing four different somatic PIK3CA pathogenic variants in five individuals.

New Homozygous Missense MSMO1 Mutation in Two Siblings with SC4MOL Deficiency Presenting with Psoriasiform Dermatitis.

Sterol-C4-methyl oxidase (SC4MOL) deficiency was recently described as an autosomal recessive cholesterol biosynthesis disorder caused by mutations in the MSMO1 (sometimes also referred to as SC4MOL) gene. To date, 5 patients from 4 unrelated families with SC4MOL deficiency have been reported. Diagnosis can be challenging as the biochemical accumulation of methylsterols can affect global development and cause skin and ocular pathology.

Promising effect of intravenous immunoglobulin therapy for epidermolysis bullosa pruriginosa.

Background: Epidermolysis bullosa pruriginosa (EBP) is rare a clinical variant of dystrophic epidermolysis bullosa characterized by trauma-induced bullae formation, milia and nail dystrophy accompanied by severe pruritus. Treatment pruritus of EBP focuses on immunosuppressive treatment with limited efficacy. Treatment strategies are not well-established.

Cytogenetic, Molecular, and Phenotypic Characterization of a Patient with de novo Derivative Chromosome 18 and Review of the Literature.

We present a patient with a de novo derivative chromosome 18 which includes a terminal deletion of 18p and a terminal duplication of 18q accompanied by a cryptic duplication of 18p. The girl had mild dysmorphic features such as micro-retrognathia, upslanted palpebral fissures, bilateral epicanthus, high palate, low-set ears, short neck, and full cheeks. She also had an H-type tracheoesophageal fistula which required surgery.

Optimizing the transport and storage conditions of current Good Manufacturing Practice -grade human umbilical cord mesenchymal stromal cells for transplantation (HUC-HEART Trial).

Background: The HUC-HEART Trial is a clinical study of intramyocardial delivery of current Good Manufacturing Practice (cGMP)-grade human umbilical cord multipotent stromal cells (HUC-MSCs) in ischemic cardiomyopathy where 2 × 10 cells are administered to peri-infarcted myocardium. Prior to the onset of the trial, we aimed to optimize the transport/storage conditions for obtaining the highest cell viability and proliferation rate of cells to be transplanted.

Methods: Cells were tested after being transported in phosphate-buffered saline (PBS) or Ringer's lactate-based (RL) transport media supplemented with human serum albumin (HSA) and/or hydroxyethyl starch (HES) at two temperatures (2-10°C or 22-24°C).
