Werner syndrome (progeria of adults) 1


Werner Syndrome (progeria of Adults) 1

General: Etiology unknown; recessive inheritance; consanguinity; second and 636c25g third decades; possible mechanisms have been proposed to explain mutation of a gene causing inhibition of deoxyribonucleic acid (DNA) synthesis and early cellular senescence.

Ocular: Absence of eyelashes and scanty eyebrows; blue sclera; juvenile cataracts; bullous keratitis; trophic corneal defects; paramacular retinal degeneration; proptosis; telangiectasia of lid; astigmatism; nystagmus; presbyopia; uveitis.

Clinical: Leanness; short stature (160 cm maximum); thin limbs; short, deformed fingers; small mouth; early baldness; stretched, atrophic skin (scleropoikiloderma); telangiectasia and trophic indolent ulcers on toes, heels, and ankles; arteriosclerosis with secondary heart failure.
