Inheritance of abnormal genes, e.g. polydactyly, ectrodactyly or brachydactyly, symptoms of deformed limbs then often occur in combination with other symptoms ; external causes during pregnancy (thus not inherited), e.g. via amniotic band syndrome; teratogenic drugs (e.g. thalidomide, which causes phocomelia) or environmental chemicals
