Translocaciones crípticas de cromosomas acrocéntricos en muestras de tejido de aborto aneuploide

Abstract: <p>Los heteromorfismos cromosómicos son variantes normales consideradas como sin impacto fenotípico. Algunos de los más frecuentes se encuentran en los brazos cortos de los cromosomas acrocéntricos (13, 14, 15, 21, 22). Recientemente se ha sugerido que un tipo de rearreglos cromosómicos, considerados heteromorfismos y conocidos como translocaciones crípticas de cromosomas acrocéntricos, podrían ser un factor causal de las alteraciones cromosómicas numéricas o aneuploidías que se abortan en 90% de los cas… Show more

“…the frequency of additional D15Z1 signals in the aneuploid offspring group was 21.9%, which is similar to a previously reported cohort of aneuploid abortions that presented the variant in 17.7% of the products, without a significant difference with the healthy population [40], although in aneuploid descendants with the polymorphism, either born alive or aborted, the acceptor chromosome was mostly 13pvar(D15Z1).…”
