This is a rare congenital anomaly, and even more rare is for the infant to survive
past the first day - month of life. There are many many more out there.
You simply could not imagine other very rare congenital abnormalities. Here's a few notable ones:
Cyclops - single eye, proboscis, holoprosencephaly (link
Twin-twin transfusion with acardiac twin "monster" variant (one twin smaller, no heart
And a more common abnormality is the neural tube dysraphic ones that include
myelomeningocele (the worst , rarest variant is sirenomyelia - mermaidism!! link
Children's and/or tertiary care ob-gyn hospitals see these much more than community
hospitals due to the nature of referrals.
And yes, they are all due to gene defects - of various types (deletions, translocations, etc)
or a bad protein expressed from the gene (mrna transcription).
Obviously we screen as best we can for neural tube defects,
but i believe ob ultrasounds should be done twice routinely. Not just one.
If you don't catch something well before 24 weeks - and even then - its a disaster.
