<\/span><\/h2>\nFocal dermal hypoplasia is a genetically inherited disorder that can affect the development of many different organ systems and was first described by Goltz in 1962. It presents with characteristic abnormalities of the skin, eyes, and teeth and can also have side effects. on the skeleton, digestive, genitourinary, neurological <\/span>and cardiovascular systems.<\/p>\nIt is a rare condition with fewer than 300 reported cases, the majority of which are women.<\/p>\n
The name is really misleading as tissue thinning is not limited to the dermis<\/span> but it also involves epidermis<\/span> and subcutaneous<\/span> tissue.<\/p>\n<\/span>How do you get focal dermal hypoplasia?<\/span><\/h2>\nFocal dermal hypoplasia<\/span> it is genetically inherited in an X-linked dominant manner. It is caused by abnormalities of the PORCN. gene<\/span> in the X chromosome<\/span>, and most often these arise in the embryo and are not inherited from a parent. The X chromosome is one of the sex<\/span> chromosomes<\/span>: females are XX, males are XY. Females with an abnormal X chromosome are affected by FDH, but most male embryos with the abnormal gene do not survive.<\/p>\nFocal dermal hypoplasia<\/span> It can affect almost any organ in the body. As with other X-linked dominant conditions, skin manifestations follow lines of development known as Blaschko lines<\/span>.<\/p>\n\n<\/span>Genetics of focal dermal hypoplasia*<\/span><\/h5>\n<\/section>\n\n\n

<\/span>What are the effects of focal dermal hypoplasia?<\/span><\/h2>\nFocal dermal hypoplasia<\/span> it can have a wide range of effects on a variety of organ systems, and the severity of the condition can vary greatly between people depending on the number of organs involved and the nature of the abnormalities.<\/p>\nSkin signs<\/p>\n
\n- \nLinear<\/span> hypoplastic (thinned) stripes that follow Blaschko's lines<\/li>\n
- Fat nodules<\/span> and fat hernia<\/li>\n
