Pain: All women have two 'X' chromosomes - potentially making them more prone to migranes

A female gene may be to blame for migraine - explaining why women are more likely to suffer from the debilitating headaches, research shows.

A study found a new region on the X chromosome as having a link to migraines, providing new evidence their might be a susceptibility gene involved.

All women have two X chromosomes while men have an X and a Y chromosome.

Researchers, led by Lyn Griffiths from Australias Griffith University, say more than one X chromosomal gene may be involved and believe a gene involved in iron regulation in the brain merits further attention.

Professor Griffiths based her study on genetic research of 300 inhabitants of remote Norfolk Isand, between Australia and New Zealand.

Many of the islanders are descended from survivors of the mutiny on the Bounty, moving there when they outgrown Pitcairn Island.

Eighty per cent of the inhabitants can trace their ancestry back to the mutiny.
