In humans, the incidence of sexual development disorders is very low, especially for rare sexual development disorders, which are even rarer. The purpose of this study is to carry out a cellular and molecular genetic study on two patients with rare sexual development disorders to explore the pathogenesis and genetic basis.In this study, samples of two patients with rare sexual development disorders were selected, and peripheral blood samples and skin tissue samples were collected. Chromosome analysis was performed by cell culture and chromosome analysis to detect whether there were abnormalities in chromosome number and structure. At the same time, genome sequencing and Sanger sequencing technologies were used to analyze their DNA sequences and screen for possible related genetic variations. In addition, real-time quantitative PCR technology was used to detect the expression levels of related genes to further explore the pathogenesis.It is expected that the research results will help to deepen our understanding of the pathogenesis and genetic basis of sexual development disorders, and provide theoretical basis and guidance for the diagnosis and treatment of related diseases.Keywords: Sexual development disorder; cellular genetics; molecular genetics; genome sequencing; real-time quantitative PCR.
