  1. Sirenomelia Mermaid Syndrome- a very rare congenital deformity in which the legs are fused together giving the appearance of a mermaid’s tail

  2. This condition is found in one out of every 100,000 live births • About as rare as conjoined twins • The syndrome can be found in all groups of people • More than half the cases result in stillbirth • Usually fatal within a day or two of birth because of abnormal kidney and urinary bladder development and function

  3. The causes of this malformation remain unknown • The discovery that it can have a genetic basis in mice represents an important step towards the understanding of its pathogenesis

  4. The mildest cases: all bones of the two fused lower limbs are discernible • The most severe cases: there is no indication that the single rudimentary lower limb is derived from the fusion of two • In some cases the legs can be separated, but complications sometimes prevent it

  5. Famous Case • Shiloh Pepin (1999-2009) was born in Maine • Lower extremities fused, no bladder, rectum, uterus, vagina, only 6 inches of large colon, one quarter of kidney, and one ovary • Only few months of life was expected • Original kidney failed at 3 months of age, went on dialysis, had a transplant at age 2, and a second transplant at age 8 • One of only three people in the world to have survived this condition for any length of time and finally died of pneumonia at the age of 10.
