طفرة جينية نادرة قد تكون سبباً لاضطراب نمائي عصبي غامض

ما يعرفه ريفو عن الخبر

اكتشف علماء تغيراً جينياً نادراً في جين بي إم بي آر 2 قد يفسر اضطراباً نمائياً عصبياً غامضاً لدى بعض الأطفال.
رصدت الدراسة التغير الجيني لدى ستة أطفال غير مرتبطين عائلياً يعانون من تأخر في النمو أو اضطراب طيف التوحد.
تسبب الطفرة في زيادة غير طبيعية في نشاط مسار إشارات حيوي يؤثر على تطور الجهاز العصبي وزيادة المشابك العصبية.
أظهرت تجارب أولية على ذباب الفاكهة إمكانية استخدام مركبات تجريبية للتحكم في النشاط المفرط لهذا المسار البيولوجي.

تجارب تكشف عن مسار بيولوجي قد يشكِّل هدفاً لبحوث علاجية مستقبلية
