Abstract

The investigation of cytogenomic and molecular alterations, through more powerful and precise methodologies and research techniques, has allowed the characterization of genetic variants with a higher degree of resolution. Establishing a correlation between the patient's phenotype and their genetic alterations is one of the main goals of research in clinical genetics. Therefore, in the project "Investigation of patients with phenotypic signs suggestive of cytogenomic rearrangements", patients referred for investigation of the diagnosis will be studied for the determination of their pathogenic mechanisms and their relationship with the phenotype. Karyotype examination, genomic array, and in cases with negative results, whole exome sequencing will be performed, and in some cases, optical genome mapping. In this way, this project will contribute to a better understanding of the human genome and its variants, in addition to the possibility of correlating the genetic variants with the phenotype of the studied patients, in order to provide a better diagnosis, prognosis, and follow-up of the patients and provide genetic counseling for the family.
