Do nail disorders run in families?

Certain nail disorders do run in families because of a genetic predisposition to a condition or illness that affects the nail. When a nail infection develops, the most common cause is a fungus. Onychomycosis is a common fungal infection that often runs in families due to an inherited sensitivity to the fungus.

Another hereditary condition that often affects people from birth is called nail-patella syndrome. Nail-patella syndrome is a condition that causes people to be born without fingernails. If a child is born with fingernails, nail-patella syndrome also can cause pitting and ridges in the nails that do exist.

Several nail disorders run in families. The most common nail infections are caused by a fungus, and some people have a genetic sensitivity to a particular fungus that can cause these infections. People with psoriasis -- who may develop nail psoriasis -- often have a relative with psoriasis, although the exact cause of the condition is not known. Ingrown toenails also tend to run in families.
