An Overview of Mutation Identification Techniques for Genetic Disorders

Abstract

A brief overview of chromosomal diseases is also provided, along with a review of the distinctive characteristics of inheritance patterns. The genetic identification of juvenile genetic illnesses is also discussed, including the use of molecular and cytogenetic techniques as well as different kinds of mutations. The objective is to teach pediatricians how to use cytogenetic and molecular techniques and tools for genetic diagnosis.  Single-gene, chromosomal, and multifactorial disorders are the three  main  types  of  genetic  diseases.  Autosomal  dominant  (AD),  autosomal recessive  (AR),  X-linked  recessive  (XR),  X-linked  dominant,  and  Y-linked (holandric) diseases are examples of single gene or Mendelian disorders that arise from mistakes in a gene's DNA sequence. Numerical and structural damage are examples of chromosomal abnormalities that cause chromosomal diseases. Genetic mutations that cause diseases have been found using cytogenetic and molecular approaches. Correct disease diagnosis is necessary for patient therapy, genetic counseling, and preventative measures.
