Congenital limb and hand anomalies

This cluster of papers focuses on genetic and developmental studies of congenital limb anomalies, including polydactyly, syndactyly, and other malformations. It explores the genetic heterogeneity, mutations in CBP and EP300 genes, disruptions in Shh regulatory elements, upper extremity development, embryology, various classification systems, and epidemiological aspects related to limb anomalies.
