Why do some people have elongated head when no one in their family does?

Question

I mean the type of head thats elongated at the expence of forehead width. Any known causes besides carniosynostosis?

Answer 1

Elongated heads must be recessive traits that can be hidden until you get a double gene for them. Or it might take a bunch of recessive genes to get a elongated head.

Answer 2

Craniosynostosis would definitely be a major contributor as in cases of cleidocranial dysostosis and so for.

Answer 3

Perhaps not all the genetic determinants of head shape are known as yet.

A very small premature is prone to develop a long narrow head, known as dolicocephaly. The condition may persist.

If a woman has a bicornuate uterus - there are several different types - her infant may have an elongated head. Most become less apparent as the child grows, but not all.
