Noonan-like syndrome with loose anagen hair is characterized by facial features suggestive of Noonan syndrome (macrocephaly, high forehead, wide-set eyes or hypertelorism, palpebral ptosis, and low-set and posteriorly rotated ears) along with hair that resembles loose anagen hair syndrome (pluckable, sparse, thin and slow-growing). Other features include frequent congenital heart defects, distinctive skin features (darkly pigmented skin with eczema or ichthyosis), short stature which may be associated with a growth hormone deficiency, and developmental delays. The condition is caused by mutations in the SHOC2 gene. It follows an autosomal dominant pattern of inheritance.
