baby from the disease
Aarskog’s syndrome, aka Aaskorg-Scott syndrome, aka faciosydigitogenital dysplasia, is a very rare hereditary disease: it occurs in one out of a million people. It manifests itself as pathological changes in the face, bones, genitals. Mostly men suffer from this disease, women are carriers of this pathology, and in them it can manifest itself only in a mild form.
Causes of Aarskog syndrome
This disease is genetic and is caused by mutations in the gene associated with the X chromosome. As you know, women have two sex X chromosomes, and men have X and Y chromosomes. They are passed on to children from their parents. This explains the fact that boys who are transmitted from the mother carrier are at risk of getting the mutated gene along with the X chromosome. In girls, even in the case of a defective gene, another chromosome remains, which compensates for the pathology. As a result, their disease manifests itself in a milder form. Continue reading
The fact that a woman’s age affects the future baby, the risk of developing pathologies in him, is known to many: when a pregnant woman is older than 35 years old, the probability of mutations in the fetus increases. But it turns out that the age of the father also matters for the health of the child.
Probability of conception
Men, unlike women, can become fathers at any age – their sperm production does not stop over the years. But sperm quality is getting worse. Sperm motility is reduced, making it harder for them to reach the egg. Their endurance decreases, and the sperm cannot penetrate the egg shell. In addition, the muscles of the perineum become weaker and do not provide the necessary contractions of the penis. Continue reading
Are mental illnesses inherited? This question worries many parents. It is very scary to “reward” your child with a mental disorder.
How are mental illnesses transmitted?
The fact that mental illness can be inherited has been noticed for a long time. Today, genetics confirm: indeed, mental disorders are more likely to appear in a child in a family where a relative suffered from a similar ailment. And the reason for this is a violation in the structure of genes.
There is such a thing as a coefficient of hereditary risk. The higher this coefficient, the higher the likelihood that the child will inherit the illness of relatives. Continue reading
