<unk>  <unk>  is a contiguous gene syndrome involving the microduplication of band 11.2 on the short arm of human chromosome 17 (17p11.2). The duplication was first described as a case study in 1996. In 2000, the first study of the disease was released, and in 2007, enough patients had been gathered to complete a comprehensive study and give it a detailed clinical description.<unk>  is named for two researchers involved in the latter phases, Drs. Lorraine<unk>  and James R.<unk>  of the Baylor College of Medicine.<unk>  was the first predicted reciprocal of a homologous recombination (microdeletion or microduplication) where both reciprocal recombinations result in a contiguous gene syndrome. Its reciprocal disease is Smith-Magenis syndrome (SMS), in which the chromosome portion duplicated in<unk>  is deleted altogether.<unk>  is considered a rare disease, predicted to appear in at least 1 in 20,000 humans.
Symptoms of the syndrome include mild mental retardation, autism, and other disorders unrelated to the listed symptoms.
Potocki-Lupski syndrome
Minkowski-Chauffard syndrome
Frasier syndrome
Mounier-Kuhn syndrome
