ANTLEY BIXLER SYNDROME PDF

POR A missense mutation in the cytochrome P reductase POR gene results in abnormal steroidogenesis related to the genital malformations often found in Antley-Bixler. Antley—Bixler syndrome is inherited in an autosomal recessive pattern, which means the defective gene is located on an autosome , and two copies of the gene one inherited from each parent are required to be born with the disorder. The parents of an individual with an autosomal recessive disorder both carry one copy of the defective gene but are usually not affected by the disorder. Diagnosis[ edit ] The diagnosis of Antley-Bixler syndrome is usually made after birth postnatally based upon a thorough clinical evaluation and characteristic physical findings. Other imaging procedures and genetic testing may also be conducted to diagnose the disorder.

E-mail: moc. Abstract Antley-Bixler syndrome ABS is rare form of craniosynostosis of both autosomal dominant and autosomal recessive inheritance.

We are reporting a female term appropriate for gestational age newborn with clinical features of frontal bossing, brachycephaly, proptosis, synostosis of radioulnar joints, hemangioma over nose and philtrum, hydrocephalus suggestive of ABS.

Only 50 cases have been reported yet. Birth weight was 2. The newborn cried at birth. Mother had an uneventful pregnancy. There was no history of intake of fluconazole during the pregnancy. There was no history of obvious congenital anomalies or fetal loss in the family. On examination, vitals were stable. Limb defects were radioulnar synostosis leading to fixed flexion deformity of elbow joints, fixed flexion deformity of both thumbs in proximal and distal interphalangeal joints, arachnodactyly, rocker-bottom feet, hallux varus, knee and hip joint contracture.

Other abnormalities were prominent chest, female genitalia with hypoplastic labia majora [ Figure 1 ].

Antley–Bixler syndrome

Antley-Bixler syndrome Antley-Bixler syndrome Antley-Bixler syndrome is a type of complex craniosynostosis named after the doctors who first described it. As well as the skull, the arms may also be affected. As we grow older, the sutures gradually fuse stick together, usually after all head growth has finished. When a child has craniosynostosis, the sutures fuse before birth. It can affect one suture or several.
