Homozygous Paternally Inherited Variant in a Patient with Canavan Disease.

Introduction: Canavan disease is an autosomal recessive disorder that causes accumulation of N-acetyl ASPArtic acid in the brain due to ASPArtoacylase deficiency with homozygous or compound heterozygous pathogenic variants in the gene located on the short arm of chromosome 17. Clinical findings are hypotonia, progressive macrocephaly, deafness, nystagmus, blindness, and brain atrophy.

Case Presentation: A one-year-old female case was evaluated in our medical genetics clinic for hypotonia, nystagmus, and strabismus.

Functional analysis of MMR gene VUS from potential Lynch syndrome patients.

Lynch syndrome is caused by inactivating variants in DNA mismatch repair genes, namely MLH1, MSH2, MSH6 and PMS2. We have investigated five MLH1 and one MSH2 variants that we have identified in Turkish and Tunisian colorectal cancer patients. These variants comprised two small deletions causing frameshifts resulting in premature stops which could be classified pathogenic (MLH1 p.

A Study of FoxO1, mTOR, miR-21, miR-29b, and miR-98 Expression Levels Regarding Metabolic Syndrome in Acne Vulgaris Patients.

Background: Acne vulgaris (AV) is an inflammatory skin disease caused by the mechanistic target of rapamycin complex 1 (mTORC1). forkhead box protein (Fox) O1 is known to regulate the relationship between the mTORC1 signaling pathway and insulin resistance (IR). Increased mTORC1 signaling is known to predispose one to diseases such as insulin resistance (IR), obesity, and diabetes mellitus.

A Case of Okur-Chung Neurodevelopmental Syndrome with a Novel, de novo Variant on the Gene in a Turkish Patient.

Introduction: Okur-Chung neurodevelopmental syndrome (OCNDS; #617062) has been associated with heterozygous mutations in the gene (*115440) mapped on the chromosome's 20p13 region.

Case Presentation: The analysis was performed on a 2-year-old patient who was admitted to our genetic diseases evaluation center by his family with a complaint of hypotonia. We detected a heterozygous NM_177559.

The Frequency of Copy Numbers in 246 Turkish Cases Analyzed with MLPA Method.

This study aimed to define the copy numbers of and genes and the diagnosis rate and carrier frequency of spinal muscular atrophy (SMA) in the Thrace region of Turkey. In this study, the frequency of deletions in exons 7 and 8 in the gene and copy numbers were investigated. A total of 133 cases with the preliminary diagnosis of SMA and 113 cases with the suspicion of being an SMA carrier from independent families were analyzed by multiplex ligation-dependent probe amplification method for and gene copy numbers.

Investigation on the Effects of Modifying Genes on the Spinal Muscular Atrophy Phenotype.

 Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder caused by the degeneration of motor neurons, muscle weakness, and atrophy that leads to infant's death. The duplication of exon 7/8 in the gene reduces the clinical severity of disease, and it is defined as modifying effect. In this study, we aim to investigate the expression of modifying genes related to the prognosis of SMA like , , , , , , , , , and  Seventeen patients, who came to Trakya University, Faculty of Medicine, Medical Genetics Department, with a preliminary diagnosis of SMA disease, and eight healthy controls were included in this study after multiplex ligation-dependent probe amplification analysis.

First Report of Jacobsen Syndrome with Dextrocardia Diagnosed with del(11)(q24q25).

Jacobsen syndrome is a rare congenital disorder that is caused by the deletion of several genes in chromosome 11. A 10-year-old female with congenital heart disease, dextrocardia, and coarse facial appearance was examined in our medical genetics clinic. Chromosome analysis and array-CGH showed a copy number loss of 9 Mb in the 11q24.

Investigation the Relationship of Autism Spectrum Disorder and Genes.

Introduction: Autism spectrum disorder is a genetically and phenotypically heterogeneous group. Genetic studies carried out to date have suggested that both common and rare genetic variants play a role in the etiology of this disorder. In our study, we aimed to investigate the effect of and gene variants in the pathogenesis of autism spectrum disorder.
