Background: X-linked mutations are highly important in clinical diagnosis, and at least 533 disorders are related to the genes located on the X chromosome.
Case Presentation: A 21-year-old Caucasian woman with a 24-year-old Caucasian man as her fiancé referred Clinical genetic lab for premarital genetic counseling (carrier screening). None of them had any abnormal manifestations.
Background: Duchene Muscular Disorder (DMD) is a severe X-linked recessive neuromuscular disease. Previous reports predicted that one-third of cases with a fatal X-linked recessive disease will be caused by a novel mutation, and the mutation rate for DMD seems to be higher in males.
Objective: A novel mutation in the DMD gene DMD (NM_004006.
As the most common type of inherited retinal degenerative disease, retinitis pigmentosa (RP) has taken clinical and prenatal attention. Considering the clinical importance of consanguineous marriages, new mutations in this type of pregnancy have a high risk and increase the importance of Prenatal Diagnosis (PND). analysis was done through Whole Exome Sequencing (WES) for a 36-year-old woman who was referred to a genetic laboratory in Kermanshah in 2021 for PND.
