Fukutin encoded by is a ribitol 5-phosphate transferase involved in glycosylation of α-dystroglycan. It is known that mutations in affect the glycosylation of α-dystroglycan, leading to a dystroglycanopathy. Dystroglycanopathies are a group of syndromes with a broad clinical spectrum including dilated cardiomyopathy and muscular dystrophy. In this study, we reported the case of a patient with muscular dystrophy, early onset dilated cardiomyopathy, and elevated creatine kinase levels who was a carrier of the compound heterozygous variants p.Ser299Arg and p.Asn442Ser in . Our work showed that compound heterozygous mutations in lead to a loss of fully glycosylated α-dystroglycan and result in cardiomyopathy and end-stage heart failure at a young age.

Elucidating the genetic contributions to Parkinson's disease (PD) etiology across diverse ancestries is a critical priority for the development of targeted therapies in a global context. We conducted the largest sequencing characterization of potentially disease-causing, protein-altering and splicing mutations in 710 cases and 11,827 controls from genetically predicted African or African admixed ancestries. We explored copy number variants (CNVs) and runs of homozygosity (ROHs) in prioritized early onset and familial cases.

Inherited retinal diseases (IRDs) constitute a heterogeneous group of clinically and genetically diverse conditions, standing as a primary cause of visual impairment among individuals aged 15-45, with an estimated incidence of 1:2000. Our study aimed to comprehensively evaluate the genetic variants underlying IRDs in the Turkish population. This study included 50 unrelated Turkish IRD patients and their families.

More than 50% of families with suspected rare monogenic diseases remain unsolved after whole-genome analysis by short-read sequencing (SRS). Long-read sequencing (LRS) could help bridge this diagnostic gap by capturing variants inaccessible to SRS, facilitating long-range mapping and phasing and providing haplotype-resolved methylation profiling. To evaluate LRS's additional diagnostic yield, we sequenced a rare-disease cohort of 98 samples from 41 families, using nanopore sequencing, achieving per sample ∼36× average coverage and 32-kb read N50 from a single flow cell.

Oocyte maturation arrest (OMA) may occur at different stages, including the germinal vesicle (GV), metaphase I (MI), and metaphase II (MII). A total maturation arrest of human oocytes is rarely observed during fertilization (IVF). We have identified a case of infertile female for whom all oocytes fail to mature and are arrested at MI.

: Sitosterolemia is a rare autosomal recessive disorder characterized by diverse clinical manifestations ranging from asymptomatic cases to the development of xanthomas, hypercholesterolemia, premature atherosclerosis, or even sudden death during childhood. It results from homozygous or compound heterozygous pathogenic variants in the or genes. Prompt detection and intervention are essential to managing this condition and preventing severe outcomes.
