An alternative treatment for type B Ulnar Polydactyly
Rudimentary ulnar polydactyly is one of the most common congenital hand anomalies. These are conventionally treated by suture ligation in the neonatal period or by formal excision, when the child is one year of age. For the last three years, the Congenital Hand Unit at Red Cross Children’s Hospital …

Maternal Effects on Embryonic and Placental Growth and the Penetrance of the Luxate Gene in Mice.
Preaxial polydactyly is one of the most frequent limb anomalies in man, and sporadically occurs in poultry, pigeons, and in the hindlimbs of cats, dogs, mice and guinea pigs (Carter, 1954). Polydactyly is detectable by the stage of footplate morphogenesis, but it is inducible before hind-limb bud …

The Misexpression of Sonic Hedgehog Leads to Digit Duplication
… exposing embryos to exogenous Shh results in polydactyly. Polydactyly is a birth defect characterized by the presence of more than the normal number of fingers or toes. This defect with or without associated malformation(s) is found to be 5 to 19 in every 10000 births. To further understand …

Birth Defect Amelioration and Placental Cytokine Expression in Mnu-Exposed Dams Treated With Ifn-Gamma
… in the distal limb malformations syndactyly, polydactyly, and webbing by 47%, 100%, and 63% respectively when IFN-gamma is given 2 days prior to MNU administration. We have also observed that IFN-gamma works at the placental level to protect against MNU-induced damage. Trophoblast loss and …

A functional and therapeutic investigation of ciliopathy proteins and ciliopathies
… mutated they can cause kidney disease, obesity, polydactyly, and retinal degeneration. In this project, I have studied craniofacial dysmorphology related to Bardet-Biedl syndrome (BBS) in humans, mice, and zebrafish, and shown there to be consistent midfacial flattening and hypoplasia. Bbs8, a …
