Atricia with papular lesions (APL) is characterized by hair loss soon after birth and the development, years later, of a diffuse papular rash over the entire skin surface. The papular rash distinguishes it from alopecia universalis (203655) (summary by Sprecher et al., 1999). [from OMIM]

Alopecia universalis congenita (ALUNC) is a severe autosomal recessive form of alopecia characterized by a complete absence of hair development affecting all scalp and body hair (Nothen et al., 1998). This rare disorder is clearly distinct from alopecia areata (AA1; 104000), which has an autoimmune basis with probable genetic predisposition. [from OMIM]
