Clinical, molecular, physiologic, and therapeutic feature of patients with CHRNA4 and CHRNB2 deficiency: A systematic review.

The α4β2 nAChRs are crucial ion channels that control neurotransmitter release and play a role in various physiologic and pathologic processes. CHRNA4 encodes the α4-nAChRs, while CHRNB2 encodes the β2-nAChRs. Recent studies have found different variants of α4β2-nAChRs in individuals with conditions such as AD, ADHD, ALS, PD, and brain abnormalities.

Homozygous mutation in causes brain abnormalities, neurodegeneration, and dysosteosclerosis (BANDDOS).

Introduction: The gene encodes the receptor for colony-stimulating factor-1, the macrophage, and monocyte-specific growth factor. Mutations in this gene cause hereditary diffuse leukoencephalopathy with spheroids (HDLS) with autosomal dominant inheritance and BANDDOS (Brain Abnormalities, Neurodegeneration, and Dysosteosclerosis) with autosomal recessive inheritance.

Methods: Targeted gene sequencing was performed on the genomic DNA samples of the deceased patient and a fetus along with ten healthy members of his family to identify the disease-causing mutation.

A novel mutation in the ALS2 gene in an iranian kurdish family with juvenile amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a rare disorder that affects both upper and lower motor neurons. Mutations in Alsin Rho Guanine Nucleotide Exchange Factor (ALS2) correlates with three similar but distinctive syndromes, including the juvenile form of ALS. An Iranian Kurdish family was involved in this study and all members were evaluated with relevant clinical guidelines.

Long non-coding RNA-associated competing endogenous RNA axes in the olfactory epithelium in schizophrenia: a bioinformatics analysis.

The etiology of schizophrenia (SCZ), as a serious mental illness, is unknown. The significance of genetics in SCZ pathophysiology is yet unknown, and newly identified mechanisms involved in the regulation of gene transcription may be helpful in determining how these changes affect SCZ development and progression. In the current work, we used a bioinformatics approach to describe the role of long non-coding RNA (lncRNA)-associated competing endogenous RNAs (ceRNAs) in the olfactory epithelium (OE) samples in order to better understand the molecular regulatory processes implicated in SCZ disorders in living individuals.

Molecular Insight Into the Therapeutic Potential of Long Non-coding RNA-Associated Competing Endogenous RNA Axes in Alzheimer's Disease: A Systematic Scoping Review.

Alzheimer's disease (AD) is a heterogeneous degenerative brain disorder with a rising prevalence worldwide. The two hallmarks that characterize the AD pathophysiology are amyloid plaques, generated via aggregated amyloid β, and neurofibrillary tangle, generated via accumulated phosphorylated tau. At the post-transcriptional and transcriptional levels, the regulatory functions of non-coding RNAs, in particular long non-coding RNAs (lncRNAs), have been ascertained in gene expressions.

An updated overview and classification of bioinformatics tools for MicroRNA analysis, which one to choose?

The term 'MicroRNA' (miRNA) refers to a class of small endogenous non-coding RNAs (ncRNAs) regenerated from hairpin transcripts. Recent studies reveal miRNAs' regulatory involvement in essential biological processes through translational repression or mRNA degradation. Recently, there is a growing body of literature focusing on the importance of miRNAs and their functions.

LRP8 (rs5177) and CEP85L (rs11756438) are contributed to schizophrenia susceptibility in Iranian population.

Introduction Schizophrenia is recognized as one of the most important mental illnesses of the last century. Many genetic and environmental factors are involved in this condition. Recently, the genome-wide association study identified two significant genes LRP8 and CEP85L associated with psychiatric disorders.

A novel splice site mutation in the SDCCAG8 gene in an Iranian family with Bardet-Biedl syndrome.

Purpose: Bardet-Biedl syndrome (BBS: OMIM 209,900) is a rare ciliopathic human genetic disorder that affects many parts of the body systems. BBS is a genetically heterogeneous disorder with a wide spectrum of clinical manifestations which makes its diagnosis and management more challenging. RetNet reports 18 genes that cause BBS and each of genes has had several known mutations.

MicroRNAs association with azoospermia, oligospermia, asthenozoospermia, and teratozoospermia: a systematic review.

Infertility is a major health problem across the world. One of the main reasons for male infertility are defects in sperm. Semen analysis is the most common test utilized to evaluate male fertility and since it suffers from multiple drawbacks, reproduction scientists have tried to find new molecular markers for detecting sperm defects.

A new report of autoinflammation and PLCG2-associated antibody deficiency and immune dysregulation (APLAID) with a homozygous pattern from Iran.

Autoinflammation and PLCG2-associated antibody deficiency and immune dysregulation (APLAID) is an autosomal dominant autoinflammatory disease characterized by episodic skin, musculoskeletal, ophthalmic and gastrointestinal tract symptoms. Here we report an 11-year-old girl with a history of repeated episodes of fever, myalgia, arthralgia, abdominal pain, and urticarial rash in the trunk and limbs. Chest and pelvic X-Ray, sacroiliac joints MRI, brain MRI and abdominal CT scan were normal.

Novel ABCD1 gene mutations in Iranian pedigrees with X-linked adrenoleukodystrophy.

Background X-linked adrenoleukodystrophy (X-ALD), the most common peroxisomal disorder, is caused by mutations in the ABCD1 gene located on Xq28. X-ALD is characterized by a spectrum of different manifestations varying in patients and families. Methods Four pedigrees with X-ALD consisting of patients and healthy members were selected for investigation of ABCD1 gene mutations.

Features, genetics and their correlation in Jalili syndrome: a systematic review.

Jalili syndrome is a rare genetic disorder first identified by Jalili in Gaza. Amelogenesis imperfecta and cone-rode dystrophy are simultaneously seen in Jalili syndrome patients as the main and primary manifestations. Molecular analysis has revealed that the gene is responsible for this rare syndrome.

RIT2: responsible and susceptible gene for neurological and psychiatric disorders.

RIT2 gene was recently introduced as a susceptibility gene in neurological disorders, a group of major problems in human society affecting millions of people worldwide. Several variants, including single nucleotide polymorphisms and CNVs, have been identified and studied in different populations. In this review, we have summarized the studies relevant to the RIT2 gene and its related disorders, including Parkinson's disease, schizophrenia, and autism.
