Genetics What influences the occurrence of hereditary diseases in a child?

Each of us is a carrier of at least 10-15 recessive mutations. And they can be inherited. That is why even absolutely healthy parents have a risk of having a baby with serious disorders.
The manifestation of certain inherited diseases in humans, according to scientists, is associated with several reasons:

• a change in the number of chromosomes;
• disorders in the structure of the parents' chromosomes;
• mutations at the gene level.

@antony10 Are there any recommendations on how to avoid diseases?

@ekaterina-gribacheva There is no escape, but you can undergo a molecular genetic study — this is a laboratory method that allows you to determine the structure of genes at the molecular level. Testing makes it possible to identify features (polymorphisms) or mutations in the structure of genes.

@antony10 Thanks for the information 😀 

@ekaterina-gribacheva 👍 

In general, mutational variability, mutations in the genetic material of cells

A lot of mutations and wrong amount of genetic material

@argentum Btw could we predict the variability and make steps against it?

@morphism   https://www.nature.com/articles/nature10665      Quite an interesting article that will answer your question)

@morphism I think not, unless it's selection or genetic engineering

@antony10 Ok, I will check that

@argentum This is a way 🙂
