Objective: The present study aims to compare the levels of 7 microRNAs (mi-RNAs) (mi-RNA-125b, mi-RNA-23a-3p, mi-RNA-146a-5p, mi-RNA-106a, mi-RNA-151a-3p, mi-RNA-28, mi-RNA-125a) in the blood of the preschool children with autism and those of their siblings with healthy controls, and to investigate the association between these mi-RNAs and the severity of autism, behavioral problems, and siblings' autistic traits.

Methods: A total of 35 children diagnosed with autism spectrum disorder (ASD) at the ages of 18-60 months (patient group), 35 non-affected siblings of the ASD group (sibling group), and 30 control subjects (control group) were involved in the study. The severity of ASD was measured using the Childhood Autism Rating Scale and the Autism Behavior Checklist (ABC).

Background: Studies on single nucleotide polymorphisms (SNPs) in non-small cell lung cancer (NSCLC) suggest that DNA repair capacity may have prognostic implications for disease recurrence and survival. However, there is no study investigating the relationship between SNPs and the risk of metastasis at the time of initial diagnosis in patients with NSCLC.

Objective: This study aimed to investigate the potential predictive value of SNPs in detecting the risk of metastasis at the time of initial diagnosis and poor prognosis in patients with NSCLC.

Article Synopsis
  • * Results showed that half of the patients had improved T-cell function after receiving immunoglobulin replacement therapy (IGRT), while B-cell issues persisted, indicating mainly antibody deficiencies.
  • * Following IGRT, there was a significant reduction in infection rates and hospitalizations, highlighting the importance of immunological assessment in pediatric patients with rare syndromes.

The short arm of chromosome 16 and especially the region 16p13.11 is a chromosome region where many structural variants, especially deletions and duplications, can be observed. Although deletions of this region are clinically well defined, duplications are rare, and so far, there is no established clinical consensus in regard with its clinical picture, and especially the dysmorphic perspective of the disease is far from being clear.

Chronic myelogenous leukemia (CML) is a myeloproliferative neoplasm caused by a translocation between the breakpoint cluster region (BCR) and Abelson murine leukemia 1 (ABL1) genes. Tyrosine kinase inhibitors (TKIs) are used in the treatment of CML. TKIs, bind the ABL1 kinase domain of hybrid BCR-ABL1 protein and inhibit its function.

Background: Cystic fibrosis, a pulmonary disease which is an autosomal recessive, inherited, multisystemic genetic disease commonly seen in the Caucasian race, is the most frequent cause of mortality and morbidity. So far, more than 2000 disease-causing gene variants have been found and this number has been increasing with the studies conducted. Although there is not yet enough data that include the Turkish population, the recent increase of studies is noteworthy.

Placental mesenchymal dysplasia (PMD) is often associated with Beckwith-Wiedemann syndrome. A 27-year-old woman with preeclampsia prematurely delivered twin girls. One side of the placenta was larger with numerous grape-like vesicles, histologically with large, cystic, stem villi with cisterns without syncytiotrophoblastic hyperplasia.

Interchromosomal effect is a controversial phenomenon postulating that during gametogenesis of translocation carriers, aside from the unbalanced segregation of chromosomes involved in the translocation, other, structurally normal chromosomes might also be affected and segregated abnormally. Here, we present a balanced reciprocal translocation carrier t(15;20)(q11;p13), and his son, bearing a different translocation of chromosome 15, t(15;Y)(q11;q12). To further elucidate the so-far-controversial interchromosomal effect phenomenon, published original articles and case reports about interchromosomal effect were reviewed.

Cystic fibrosis is a chronic multisystemic disease originating from functional alterations in CFTR (cystic fibrosis transmembrane conductance regulator) protein. To date, more than 300 pathogenic variants have been described in the literature. However, the diagnosis of CF, which was thought to become easier after the gene was identified, became more complicated due to the enormous amount of variations.

Article Synopsis
  • The study investigated the relationship between specific eNOS gene polymorphisms and ischemic stroke in the Anatolian population, involving 112 stroke patients and 160 controls.
  • Researchers used real-time polymerase chain reaction (RT-PCR) to analyze genetic variations and compared the frequency of alleles and genotypes between the groups.
  • Results showed no significant link for the G894T and T786C polymorphisms with stroke risk, but the intron 4 VNTR polymorphism was associated with a higher stroke risk in patients.

Background: Klinefelter syndrome(KS), affecting 1 in 500-1,000 newborn males, is the most common sex chromosome aneuploidy among males with primary hypogonadism. Isochromosome Xq on the other hand is a rare variant of Klinefelter syndrome, accounting approximately 0.3% of all KS and associated with normal height and androgenisation compared to classical KS.

Intervertebral disc degeneration (IVDD) is a common degenerative spinal condition. Recent studies have shown that the incidence of disc herniation and disc degeneration may be explained by genetic factors.  In this study, we investigated the link between various polymorphic variants of the vitamin D receptor (VDR), matrix metalloproteinase 2 (MMP2), and insulin like growth factor 1 receptor (IGF1R) genes and IVDD in patients with IVDD, in Turkey.

  • * The study investigates the role of variations in the NAT2 gene, which helps metabolize drugs and toxins, in relation to psoriasis susceptibility by comparing 260 psoriasis patients to 200 healthy controls.
  • * Findings show no significant differences in NAT2 gene variations between the two groups; however, certain polymorphisms are linked to earlier onset age and increased severity of psoriasis in those affected.

Inversion occurs after two breaks in a chromosome have happened and the segment rotates 180° before reinserting. Inversion carriers have produced abnormal gametes if there is an odd number crossing- over between the inverted and the normal homologous chromosomes causing a duplication or deletion. Reproductive risks such as infertility, abortion, stillbirth and birth of malformed child would be expected in that case.

Identification of biomarkers used for the prognostic evaluation of non-small cell lung cancer (NSCLC) patients is important. The aim of this study was to evaluate the potential prognostic value of XRCC1, ERCC1, ERCC2, and TP53 single nucleotide polymorphisms (SNPs) in completely resected NSCLC patients. In total, 130 patients, surgically treated for NSCLC between 2000 and 2012, were included.

GAPO syndrome (OMIM#230740) is the acronym for growth retardation, alopecia, pseudoanodontia, and optic atrophy. About 35 cases have been reported, making it among one of the rarest recessive conditions. Distinctive craniofacial features including alopecia, rarefaction of eyebrows and eyelashes, frontal bossing, high forehead, mid-facial hypoplasia, hypertelorism, and thickened eyelids and lips make GAPO syndrome a clinically recognizable phenotype.
