Â This syndrome can also cause severe malformations of other parts of the body, ... | Is tetra-amelia syndrome inherited ? | In most of the families reported so far, tetra-amelia syndrome appears to have an autosomal recessive pattern of inheritance. Autosomal recessive inheritance means both copies of the gene in each cell have mutations. The parents of an individual with tetra-amelia syndrome each carry one copy of the mutated gene, but do... |
