Indels are highly abundant in human genomes and have contributed massively to genome evolution. However, the role of indels and their underlined mechanisms of mutagenesis in Mendelian disorders still needs to be appreciated. To explore the contribution of indels in a monogenic disorder, we analyzed all indels already described in the AR gene, including three novel indels found in our cohort. We analyzed the indel distribution through the AR coding region, compared wit...

Background: Disorders of Sex Development (DSD) comprise several phenotypes due to dysfunction in genes involved in human sexual determination and differentiation. The most frequent aetiologies among 46,XY DSD are androgen insensitivity syndrome and 5-alpha-reductase type 2 deficiency due mutations in AR and SRD5A2 genes, respectively.Objective and hypotheses: The purpose of this study was to investigate mutations in AR and ...
