Psychiatric disorders are highly inheritable, and most psychiatric disorders exhibit genetic overlap. Recent studies associated the 3q29 recurrent deletion with schizophrenia (SCZ) and autism spectrum disorder (ASD). In this study, we investigated the association of genes in the 3q29 region with SCZ and ASD. and were chosen as candidate genes for this study based on evidence from previous research. We sequenced and in 437 SCZ cases, 187 ASD cases and 524 controls in the Japanese population. Through targeted sequencing, we identified 6 missense variants among the cases (ASD & SCZ), 3 missense variants among controls, and 1 variant common to both cases and controls; however, no loss-of-function variants were identified. Fisher's exact test showed a significant association of variants in among cases (p=0.0160). These results suggest variants affect the etiology of SCZ and ASD in the Japanese population. Further research examining 3q29 region genes and their association with SCZ and ASD is thus needed.

Background: Chromosome 3q29 duplication syndrome is a rare chromosomal disorder with a frequency of 1:5000 in patients with a neurodevelopmental phenotype. The syndrome is characterized by phenotypic polymorphism and reduced penetrance.
Methods: Patients were investigated by performing a cytogenetic analysis of GTG-banded metaphases, aCGH with the SurePrint G3 Human CGH Microarray 8×60K, qPCR, FISH, and WES.

Background: A complex inheritance has been suggested in families with colorectal-, gastric- and prostate cancer. Therefore, we conducted a genome-wide association study (GWAS) in colorectal cancer patients, who's relatives had prostate-, and/or gastric cancer.
Methods: The GWAS analysis consisted of 685 cases of colorectal cancer and 4780 healthy controls from Sweden.

Article Synopsis
- The study focuses on understanding the molecular changes in adenoma and carcinoma components of colorectal tumors to better grasp early cancer development.
- Researchers analyzed genetic alterations in 46 cases of microsatellite-stable colorectal cancer using genome-wide methods, identifying two distinct subgroups based on the frequency of somatic copy number alterations (SCNAs).
- Findings revealed that while both adenoma and carcinoma components shared common mutations, significant SCNAs and increased TP53 mutations were essential for the transition from adenoma to carcinoma within these tumors.

Schizophrenia is a neuropsychiatric disorder characterized by various symptoms such as hallucinations, delusions, and disordered thinking. The etiology of this disease is unknown; however, it has been linked to many microdeletion syndromes that are likely to contribute to the pathology of schizophrenia. In this review we have comprehensively analyzed the role of various microdeletion syndromes, like 3q29, 15q13.
