Autosomal recessive amelia is characterized by the absence of the upper limbs and severe underdevelopment of the lower limbs. Minor facial abnormalities (depressed nasal root, upturned nose, infra-orbital creases, prominent cheeks and micrognathia) were also reported. The syndrome has been described in three fetuses born to non consanguineous parents.
Features include: Amelia.
TBX4 function has not been fully characterized.
Autosomal recessive amelia is associated with mutations in the TBX4 gene on chromosome 17.
Genetic testing for TBX4 is available. Testing is considered confirmatory for diagnosis.
No clinical trials have been registered for autosomal recessive amelia.
3 publications have been identified in PubMed for autosomal recessive amelia. Research spans Review / Meta-Analysis (33%), Case Report / Case Series (33%), and Basic Science / Preclinical (33%).
