Cases of skin disease that may be inherited in this kind of mode include epidermolysis bullosa simplex (EBS), acute intermittent porphyria, white sponge nevus, ichthyosis, epidermolytic palmoplantar keratoderma, hereditary benign intraepithelial dyskeratosis and so on. Autosomal recessive inheritance
The second kind is autosomal recessive inheritance, in this kind of inheritance, patients can be of any sex and inbreeding tends to lead to this inheritance. Cases of skin disease that may be inherited in this kind of mode include epidermolysis bullosa, xeroderma pigmentosum, acrodermatitis enteropathica, ichthyosis and so on. X-linked dominant inheritance
The third kind is X-linked dominant inheritance, in this kind of inheritance, patients can be of any sex. Male patients can pass the disease on to their sons and the chances of female patients passing it to their daughters or sons are almost equal. Cases of skin disease that may be inherited in this kind of mode include incontinentia pigmenti, focal dermal hypoplasia and so on. X-linked recessive inheritance
The last kind is X-linked recessive inheritance, in this kind of inheritance, patients can be of any sex and the prevalence in men is higher than that in women. Male patients cannot pass the disease on to their sons. Cases of skin disease that may be inherited in this kind of mode include fabry disease, anhidrotic ectodermal dysplasia, dyskeratosis congenita and so on. Multiple gene (polygenic)
Multiple-gene inheritance of genodermatosis refers to the inheritance of a skin disease caused by multiple genetic abnormalities.
Hidrotic ectodermal dysplasia
Hidrotic ectodermal dysplasia is a rare genodermatosis which is also known as Clouston syndrome. The patients nails may be too thick, too brittle, too bent or have different colors, their hair also appear mottled, sparse and other abnormalities. These symptoms often begin when the patient is an infant. Diagnostic methods
Genodermatosis is often rare and varied, but diagnostic methods have some commonalities, the diagnosis of rare genodermatosis is basically divided into six steps: 1. Each genodermatosis has different clinical manifestations. People can observe the special features and changes of the skin to judge whether they are sick or not. Features will be different in different age groups, so it is necessary to observe and record the special features of the skin in each age group; 2. Genodermatosis is a hereditary disease, knowing as much as possible about a detailed and complete family history helps in screening and diagnosis; 3. People can do a detailed physical examination to observe the special features and manifestations of other organs besides skin. It can help to narrow down the disease and make a definitive diagnosis; 4. People can carry out laboratory tests such as skin biopsies with high-tech and precise scientific instruments to have further results; 5. Different genodermatosis and their clinical manifestations may be caused by abnormalities in the same gene, and abnormalities in different genes may also lead to the same clinical manifestations. In order to have a definitive diagnosis or identify complex and specific types of genodermatosis, genotype–phenotype correlation needs attention; 6.
