Clinical characterizations and molecular genetic study of two co-segregating variants in PDZD7 and PDE6C genes leading simultaneously to non-syndromic hearing loss and achromatopsia.

Background: Autosomal recessive non-syndromic hearing loss (NSHL) and cone dystrophies (CODs) are highly genetically and phenotypically heterogeneous disorders. In this study, we applied the whole exome sequencing (WES) to find the cause of HL and COD in an Iranian consanguineous family with three affected individuals.

Methods: Three members from an Iranian consanguineous family who were suffering from NSHL and visual impairment were ascertained in this study.

A Novel Germline Pathogenic Variant of Gene in an Iranian Pedigree with Familial Squamous Cell Carcinoma: A Brief Report.

Squamous cell carcinoma (SCC) is the most common human solid tumor and the leading cause of cancer death. SCC of the breast is a very rare type of cancer that has not been well researched. Early identification of the genetic factors involved can lead to early diagnosis and targeted treatment.

Novel in-frame duplication variant characterization in late infantile metachromatic leukodystrophy using whole-exome sequencing and molecular dynamics simulation.

Metachromatic leukodystrophy (MLD) is a neurodegenerative lysosomal storage disease caused by a deficiency in the arylsulfatase A (ARSA). ARSA deficiency leads to sulfatide accumulation, which involves progressive demyelination. The profound impact of early diagnosis on MLD treatment options necessitates the development of new or updated analysis tools and approaches.

Whole exome sequencing identified a novel LAMA2 frameshift variant causing merosin-deficient congenital muscular dystrophy in a patient with cardiomyopathy, and autism-like behavior.

Muscular dystrophy (MD) is a group of multiple muscle diseases, which causes severely impaired motor ability, degeneration and dysfunctions in the musculoskeletal system, respiratory failure and feeding difficulties. LAMA2-related MD is caused by pathogenic variants in the LAMA2 gene, encoding laminin a2 chain, a component of the skeletal muscle extracellular matrix protein laminin-α2β1γ1. We performed clinical examination and molecular genetic analysis in a patient with congenital MD (CMD), and autism-like phenotype.

Trends of human brucellosis in Central Iran (2010-2018).

Background: Brucellosis is one of the most common infectious diseases worldwide which is caused by direct contact with affected animals or their products. It puts a huge impact on the economy, society, and the environment. Iran is the fourth endemic country for brucellosis in the world.

Whole-Exome Sequencing Identifies a Recurrent Small In-Frame Deletion in MYO15A Causing Autosomal Recessive Nonsyndromic Hearing Loss in 3 Iranian Pedigrees.

Background: Hearing loss (HL) is the most prevalent and genetically heterogeneous sensory disabilities in humans throughout the world.

Methods: In this study, we used whole-exome sequencing (WES) to determine the variant causing autosomal recessive nonsyndromic hearing loss (ARNSHL) segregating in 3 separate Iranian consanguineous families (with 3 different ethnicities: Azeri, Persian, and Lur), followed by cosegregation analysis, computational analysis, and structural modeling using the I-TASSER (Iterative Threading ASSEmbly Refinement) server. Also, we used speech-perception tests to measure cochlear implant (CI) performance in patients.

Whole exome sequencing identifies novel compound heterozygous pathogenic variants in the MYO15A gene leading to autosomal recessive non-syndromic hearing loss.

Autosomal recessive non-syndromic hearing loss (ARNSHL) is a highly heterogeneous disease, for which more than 70 genes have been identified. MYO15A mutations have been reported to cause congenital severe-to-profound HL. In this study, we applied the whole exome sequencing (WES) to find the cause of HL in an Iranian family.

A novel pathogenic variant in the LRTOMT gene causes autosomal recessive non-syndromic hearing loss in an Iranian family.

Background: Hearing loss (HL) is the most common sensorineural disorder with high phenotypic and genotypic heterogeneity, which negatively affects life quality. Autosomal recessive non-syndromic hearing loss (ARNSHL) constitutes a major share of HL cases. In the present study, Whole exome sequencing (WES) was applied to investigate the underlying etiology of HL in an Iranian patient with ARNSHL.

Epigenetics and Common Non Communicable Disease.

Common Non communicable diseases (NCDs), such as cardiovascular disease, cancer, schizophrenia, and diabetes, have become the major cause of death in the world. They result from an interaction between genetics, lifestyle and environmental factors. The prevalence of NCDs are increasing, and researchers hopes to find efficient strategies to predict, prevent and treat them.
