Biology:Buttien-Fryns syndrome
From HandWiki
Short description: Congenital genetic disorder which causes oligodactyly and micrognathia
Buttien-Fryns syndrome is a congenital genetic disorder that causes severe oligodactyly and micrognathia. It is caused by a change in the structure of the 10q gene.[1] The condition has been reported in four patients, two of which were siblings.[2]
Cause
Buttien-Fryns syndrome is caused by a duplication or triplication of the 10q24 gene.[3] This gene is also associated with other conditions such as split hand.[1] The condition is inherited in an autosomal recessive manner.[4]
Symptoms
Oligodactyly and micrognathia are the most well known symptoms of the disease. Other symptoms include:[4]
- Ankle and foot anomalies
- Nearsightedness
- Kidney hypoplasia/insufficiency
- Maxilla hypoplasia
- Microretrognathia
- Wrist and hand anomalies
- Ear anomalies
- Ulna anomalies
- Hearing loss
- Cryptorchidism
- High-arched palate
- Nystagmus
- Microglossia
- Microdontia
- Macrocephaly
- Cleft palate
- Other oral anomalies
