Study: إنجاب الرقل في سن متحدد يزيد تحميل الطفرات الورائية

A new study revealed that the father’s age increases the risk of inheritance, but the overall probability of genetic defects remains low among most families.

The analysis of the study at the Wellcome Sanger Institute for participants between 24 and 74 years showed that between 3% and 5% of men’s male reproductive organs Middle-aged and older, they have mutations associated with growth disorders or childhood cancers, according to “Stadiy Faynds”.

The number of mutations increases with age, due to the competition between stem cells in the tests, and this is the form of the competition Al-Khalwi gives some of the harmful features the advantage of survival, and the danger comes from it.

And according to the researchers, about 2% of men’s infected animals in their 30s are likely to cause the disease, if it leads إلى الحمل, وبحلو الـ 70, تُصْرِيّة الطفرة تُصربة على 4.5%, وحدود فيق 40 جيناً تُمنح بيحة التفرات هذا عنيقة competition. في هذا لم تعلبة لا على 13 جيناً من هذا الذهب.

Most of these 40 genes are associated with developmental disorders or childhood cancers, so when children inherit mutations in these genes, they They suffer from conditions such as Noonan’s syndrome, Mayer’s syndrome, or those who are preparing for cancer.

وتثثر على التفرة على النموذ و قاعدة فيق, كما على على النمو قلب و على عرض العربية.

The researchers said: “Unlike the chromosomal abnormalities associated with the mother’s age, which can be checked with prenatal tests, such as Altfrat connected with عمر الاب تحدياً different. they are rare individually but common collectively”.

And this pattern makes the traditional test difficult. وسیکون کوکہ کے ہے ہے ہے ہے ہے ہے These conditions are so rare that they are not detected even by using advanced tests.
