Will fathers pass on ichthyosis to their children?

Zhang Jian's therapy divides ichthyosis into four types: ichthyosis vulgaris, sex-linked ichthyosis, lamellar ichthyosis and bullous ichthyosis; The symptom picture is as follows:

Common type:

Sexual relations:

Lamination type:

Bullous type:

You can see what kind of ichthyosis you are by comparing the pictures. Of course, the symptoms of different types of ichthyosis are similar. If you are not sure what type it is, you can ask a doctor for a diagnosis.

Next, talk about the characteristics and genetic laws of these kinds of ichthyosis.

First of all, ichthyosis vulgaris is one of the most common ichthyosis, with a high incidence, which belongs to autosomal dominant genetic disease. Children who marry normal people, regardless of sex, have a 50% chance of getting sick.

Secondly, sex-linked ichthyosis, as its name implies, is related to gender. Most of the patients are male and belong to X chromosome recessive genetic disease. The male patient is married to a normal person, and the son is also normal, and does not carry the pathogenic gene. 65,438+0,000% of their daughters carry disease-causing genes, but their skin is normal. 50% of their sons born to female carriers are sick, and 50% of their daughters carry disease-causing genes.

Lamellar ichthyosis and bullous ichthyosis are very serious types, which are relatively rare in clinic, but they are also genetic diseases. It is recommended to go to a regular hospital for diagnosis.

Father has ichthyosis, usually common or sexually linked ichthyosis. If it is common ichthyosis, then the offspring have a 50% probability of inheriting the disease. If it is sex-linked ichthyosis, then the sons are normal and the daughters are normal, but 100% carries the pathogenic gene.
