Summaries for Antley-Bixler Syndrome with Genital Anomalies and Disordered...

OMIM : 53 The Antley-Bixler syndrome (ABS) is an exceptionally rare craniosynostosis syndrome characterized by radiohumeral synostosis present from the perinatal period. There is a wide spectrum of anomalies seen in ABS; other features include midface hypoplasia, choanal stenosis or atresia, multiple joint contractures, visceral anomalies (particularly of the genitourinary system), and impaired steroidogenesis (present only in patients with POR mutations). Mortality has been reported to be as high as 80% in the neonatal period, primarily due to airway compromise, and prognosis improves with increasing age (summary by McGlaughlin et al., 2010). (201750)

MalaCards based summary : Antley-Bixler Syndrome with Genital Anomalies and Disordered Steroidogenesis, also known as abs1, is related to cytochrome p450 oxidoreductase deficiency and disordered steroidogenesis due to cytochrome p450 oxidoreductase deficiency, and has symptoms including malar flattening, hypertelorism and frontal bossing. An important gene associated with Antley-Bixler Syndrome with Genital Anomalies and Disordered Steroidogenesis is POR (Cytochrome P450 Oxidoreductase). Affiliated tissues include ovary, kidney and placenta.

UniProtKB/Swiss-Prot : 71 Antley-Bixler syndrome, with genital anomalies and disordered steroidogenesis: A disease characterized by the association of Antley-Bixler syndrome with steroidogenesis defects and abnormal genitalia. Antley-Bixler syndrome is characterized by craniosynostosis, radiohumeral synostosis present from the perinatal period, midface hypoplasia, choanal stenosis or atresia, femoral bowing and multiple joint contractures.
