The chances of passing on ichthyosis to the next generation in a woman cannot be generalized and are usually related to the cause of the ichthyosis. Clinically, ichthyosis is divided into acquired and hereditary. The former is often secondary to other diseases, such as tumors, etc., and usually will not be inherited to the next generation; while the latter is mainly divided into five categories, as follows: 1. Ordinary ichthyosis, congenital herpetic ichthyosis-like erythroderma: the former belongs to the semi-dominant inheritance, that is, the individual carrying the disease-causing gene symptoms vary in severity; the latter belongs to the autosomal dominant inheritance, as follows: (1) A mother who is heterozygous has a 100% chance of having the disease in her offspring, regardless of whether the father has the disease or not; (2) If the mother is heterozygous and the father does not have the disease, the probability of her offspring having the disease is 50%; if the father is heterozygous, the probability of her offspring having the disease is 75%. (3) If the mother is heterozygous and the father is heterozygous, the probability of the offspring being affected is 100%; 2. Sex-linked ichthyosis: This is an X-linked recessive disorder. If the mother has the disease, the probability of having a boy is 100%. The chance of having a girl depends on whether the father is sick or not: if both parents are sick, the chance of having a girl is 100%; if the mother is sick and the father is normal, the chance of having a girl is 0%. 3. Laminar ichthyosis, congenital non-herpetic ichthyosis-like erythroderma: autosomal recessive inheritance. Both parents have the disease, the offspring of 100% chance of disease. When the mother is sick, the father is normal, the offspring of the probability of disease depends on whether the father carries the disease-causing genes: if the father does not carry the disease-causing genes, the probability is 0%; if the father carries the disease-causing genes, the probability is 50%. It is recommended that the patient be diagnosed under the guidance of a professional doctor and, if necessary, undergo gene sequencing to further determine the probability of inheritance.
