"The presence of a true human tail in neonates is a rare congenital anomaly and should be investigated through physical and radiological examinations in a comprehensive manner," the journal article mentions. Before the delivery, an ultrasound revealed no concerns or signs regarding a tail being attached to the child's nervous system. The report says the unidentified infant was delivered at 35 weeks without any complications. The case is extremely rare, as it was said that there have only been about 40 documented cases of children being born with true, boneless, tails in history. The tail, in this particular case, continued to grow.īy the time the child was born prematurely at 35 weeks, he sported a 6-inch posterior protuberance with a 1.5 inch-wide ball at the tip like a meaty medieval mace, Daily Mail reported.ĭoctors who examined the baby noted the tail contained no parts made of cartilage and bone, meaning it was a rare example of a true human tail. In the next couple weeks of development, however, the tail disappears, and over time the vertebrae fuse to form the coccyx, or tailbone, in the adult. However, the growth is quickly absorbed by the body, culminating in the creation of the tailbone. The unnamed infant’s “epic tail” began sprouting in the womb where, like all babies, he developed an embryonic appendage around four to eight weeks after gestation. A ccording to a case study in the Journal of Pediatric Case Surgery Reports, There are very few babies ever to be born with a true human tail. How and why some primates like humans lost their tails is largely a mystery, but a new study suggests a single genetic mutation may be responsible for the sudden change. That ape then passed the trait down to its offspring and the mutation continued to rapidly make its way down several genealogies until it reached us.Doctors in Brazil were left flabbergasted over the case of a boy born with a true human tail - a “rare congenital anomaly." This led Xia and colleagues to hypothesize that 20 million years ago, a random gene mutation in an ape caused it to either develop a shortened nub of a tail or no tail at all. Human Tail: A Benign Condition Hidden Out of Social Stigma and Shame in Young Adult - A Case Report and Review Authors Pramod Janardan Giri 1, Vaibhav Sharadrao Chavan 1 Affiliation 1 Department of Neurosurgery, Super Speciality Hospital and Government Medical College, Nagpur, Maharashtra, India. The base of the coccyx is formed by the first and broadest coccygeal vertebra, Co1, which sits immediately below S5, the 5 th sacral vertebra. ![]() They found that the addition of the TBXT gene resulted in some mice having no tails while others developed short, stubby tails. To test the theory that this gene was the genetic mechanism responsible for tail loss in humans, Xia and his team genetically modified mice embryos to see what would happen. The presence of tails in humans is extremely infrequent 2. Higher incidences of spinal dysraphism (49.15) and tethered spinal cord. In reviewing the literature from 1960 to 1997, 59 cases were described. ![]() Lipoma accompanied by tethered spinal cord were found. A newborn with a tail-like structure over the coccygeal area observed since birth is presented. Angie Selman / EyeEm // Getty ImagesĪfter comparing the apes and monkeys, Xia made an exciting discovery: a mutation in the TBXT gene was evident in humans and apes but not seen in monkeys. Introduction A caudal appendage or human tail is a dorsal protrusion in the lumbar, sacrococcygeal, or para-anal region, that is usually diagnosed after birth 1. The human tail is a congenital anomaly with a protruding lesion from the lumbosacrococcygeal region. Using a primer-extension/nick-translation technique and nondenaturing hybridization, we find long 3 G-rich tails at human chromosome ends in mortal primary. A genetic mutation caused the felines to lose their tails but some are still born with short nubs for tails while others actually develop regular-sized tails. The Manx cat, famous for lacking a tail, is from the Isle of Man. Further Particulars Respecting the Race of Human Beings with Tails, Discovered by Mr. ![]()
