Cytogenetics and FISH
Cytogenetics and FISH
Chromosome structure changes can affect how well the body’s systems grow, develop, and function. Numerous genes along the chromosome may be impacted by these changes, which could also cause problems with the proteins produced by those genes.
Cytogenetic laboratories at Roya offer cutting-edge genetic laboratory testing of the highest quality. We provide diagnostic services that combine cutting-edge technology with expert clinical advice and genetic counseling to aid in the early detection, and effective management of inherited disease, cancer, and infertility.
The Roya Cytogenetic lab provides comprehensive testing services including:
- Standard karyotyping: Standard G-banding chromosomal analysis are performed on all tissue types for diagnosis of congenital anomalies and hematological disorders and solid neoplasms
- FISH (Fluorescence in situ hybridization): A technique used for the detection of subtle chromosomeal changes not chrachterized by conventional cytogenetic using a number of different types of probes.
Comparative genomic hybridization (Array CGH)
A significant methodological development in traditional cytogenetics is array CGH, commonly called microarray analysis. In order to identify unclear dysmorphic, retardation, and malformation diseases, array CGH is employed to detect losses or gains of genomic areas in chromosomal material. Microarray analysis detects genomic abnormalities with a diagnostic resolution of 50–100 kb. Traditional chromosomal analysis has a detection limit of 5–10 Mb.
