Having six or more café au lait spots greater than 5 mm in diameter before puberty, or greater than 15 mm in diameter after puberty, is a diagnostic feature of neurofibromatosis type I (NF-1), but other features are required to diagnose NF-1. [2] Familial multiple cafe-au-lait spots have been observed without an NF-1 diagnosis. [9] Noonan syndrome
Lisch nodules as seen in NF1 Person with multiple small neurofibromas in the skin and a "café au lait spot" (bottom of photo, to the right of centre). A biopsy has been taken of one of the lesions. Neurofibromatosis type 1 in early life may cause learning and behavior problems – about 60% of children who have NF1 have mild difficulty in ...
It was first discovered when Riccardi et al. described multiple families with cafe-au-lait spots and no association for neurofibromatosis in 1980. [5]In 1993, Charrow et al. described five members from a four-generation family who had the characteristic tell-tale sign of neurofibromatosis, multiple cafe au lait spots; however, testing of the gene usually involved in neurofibromatosis revealed ...
Legius syndrome (LS) is an autosomal dominant condition characterized by cafe au lait spots. [3] It was first described in 2007 and is often mistaken for neurofibromatosis type I. It is caused by mutations in the SPRED1 gene. [5] [6] It is also known as neurofibromatosis type 1-like syndrome. [1]
Café au lait spot characteristic of NF1 Diagnostic criteria of neurofibromatosis type I, requiring at least 2 of the mentioned items. [6]The following is a list of conditions and complications associated with NF-1, and, where available, age range of onset and progressive development, occurrence percentage of NF-1 population, method of earliest diagnosis, and treatments and related medical ...
In 1956 Crowe et al. recognised the autosomal dominant heredity of neurofibromatosis and the use of 6 or more café au lait spots to diagnose the condition. In 1964 Crowe published work on the use of axillary freckling in its diagnosis, which is now referred to as the Crowe sign.

[30] [31] Café-au-lait spots are the most common sign of NF1, but other symptoms include lisch nodules of iris, cutaneous neurofibromas (CNF), plexiform neurofibromas (PN), skeletal defects, optic nerve gliomas, life-threatening malignant peripheral nerve sheath tumors (MPNST), attention deficits, learning deficits and other cognitive ...
