Heřmanský–Pudlák syndrome (often written Hermansky–Pudlak syndrome or abbreviated HPS) is an extremely rare autosomal recessive[1] disorder which results in oculocutaneous albinism (decreased pigmentation), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin).
It is thought to affect around 1 in 500,000 people worldwide, with a significantly higher occurrence in Puerto Ricans, with a prevalence of 1 in 1800.
The defective gene, called HSP [dubious – discuss], responsible for this disorder is located on the long arm of chromosome 10 (10q2).
Fifty percent of their children risk being carriers of the disease, but generally will not show symptoms of the disorder.
Molecular testing of the HPS3 gene is available on a clinical basis for individuals of central Puerto Rican or Ashkenazi Jewish heritage.
[11] While there is no cure for HPS, treatment for chronic hemorrhages associated with the disorder includes therapy with vitamin E and the antidiuretic dDAVP.
Since patients with the syndrome have bleeding tendencies, intraoperative, perioperative, and postoperative hemorrhages should be prevented and treated.
The major complication of most forms of the disorder is pulmonary fibrosis, which typically exhibits in patients ages 40–50 years.
