چکیده
Descripción: los trastornos del desarrollo sexual (DSD, disorders of sex development) son condiciones congénitas que se caracterizan por la discordancia entre apariencia externa (masculinidad o feminidad) y constitución cromosómica sexo gonadal. Estas manifestaciones están relacionadas con alteraciones a nivel gonadal tracto urinario-genital e incluso sistema reproductivo-endocrino. Dentro de las causas estas encuentran genéticas, cuales provocadas anomalías cromosómicas, en particular cromosomas sexuales, alteración genes involucrados el embrionario órganos sexuales; como también, generen interrupción síntesis hormonas específicas. Relevancia: grupo ligado número síndrome Klinefelter (47,XXY) (SK) Turner (45,X) (ST). Reportes literatura mencionan aneuploidias sexuales impactan directamente genes, factores transcripcionales mecanismos epigenéticos afectan expresión génica. Conclusiones: literatura, escasos estudios moleculares comparativos pacientes (ST) (SK), siendo estos fundamentales para comprender procesos génicos relacionados patologías pacientes, así contribuir al mejoramiento diagnóstico, tratamiento asesoría médica paciente ST ó SK, impactando calidad vida estos.

متن کاملDisorders of Sexual Differentiation and Sex Development
The determination of a baby’s sex begins at the chromosomal level with the insemination of the ovum. Further sexual differentiation follows during the subsequent embryogenesis. However, chromosomal anomalies, gene mutations, and other exogenous or endogenous factors can cause disorders of sexual differentiation. These disorders manifest during childhood or at the latest in puberty, making patie...
