I am trying to find my grandfather's family. He was born ca 1890's. He had a hereditary disease that was past on to his son. The condition effects the palms of hands & soles of feet - they have a hardened surface (like wook) noticeable from birth. The doctors call it "keratoderma" - Keratoderma of the palms and soles is a pathologic condition characterised by diffuse or localised thickening of the stratum corneum which may be part of a generalised condition or a disorder that primarily involves the hands and feet.
Does anyone know of anyone with the same condition or have it in there family?
