Renpenning syndrome is a group of X-linked mental retardation syndromes, caused by mutations in human polyglutamine-binding protein 1 (PQBP1) gene. It is characterized by intellectual deficiency, microcephaly, short stature, and microrchidia. PQBP1 plays important roles in neurodevelopment and neuronal functions. It is thought to interact with RNA polymerase, transcription factors, and spliceosome proteins, and thus to act as a transcription and splicing regulator.
It has been demonstrated that five named XLMR syndromes (Sutherland-Haan, Hamel cerebropalatocardiac, Golabi-Ito-Hall, Porteous, and Renpenning), one nonsyndromic family (MRX55), and three small XLMR families have PQBP1 mutations. Since 2003, they are grouped under the common name of Renpenning syndrome.

タイトル
Novel truncating mutations in the polyglutamine tract binding protein 1 gene (PQBP1) cause Renpenning syndrome and X-linked mental retardation in another family with microcephaly.
