Sex differentiation and development are complex processes reflecting the precise spatiotemporal expression of specific genes and interactions among gene products. In some instances, peripheral blood karyotype diverges from anticipated findings based on phenotypic features. Ascertaining for chromosomal mosaicism aids the shared decision-making discussions with families and other health care providers. We have investigated for sex chromosome mosaicism in 13 patients by using flu...

Background: Early genetic diagnosis in patients with disorders of sex development (DSDs) can facilitate clinical management, predict recurrence risks, and augment general knowledge. Novel techniques such as SNP microarrays, GWAS, and exome sequencing have identified mutations in the coding regions of genes linked to DSDs. In some instances, variants in non-coding regions have been associated with 46,XY gonadal dysgenesis, e.g. deletions upstream of SOX9 (PLoS One 2011...
