Congenital Circumscribed Hypertrichosis

Congenital Nevoid Hypertrichosis

Acquired Hypertrichosis lanuginosa

Acquired Generalized Hypertrichosis

Acquired Localised Hypertrichosis

Acquired Patterened Hypertrichosis

Congenital Hypertrichosis lanuginosa is caused due to paracentric inversion mutation of q22 band of chromosome 8. It is of autosomal dominant form.

Congenital Generalized Hypertrichosis is linked to chromosome Xq24-27.1.
