Gray platelet syndrome, or platelet alpha-granule deficiency,OMIM|139090] is a rare congenital bleeding disorder caused by a reduction or absence of the platelet alpha-granules in blood platelets, or of the proteins contained in these granules. [cite journal |author=Nurden AT, Nurden P |title=The gray platelet syndrome: clinical spectrum of the disease |journal=Blood Rev. |volume=21 |issue=1 |pages=21–36 |year=2007 |pmid=16442192 |doi=10.1016/j.blre.2005.12.003 |url=]

It is generally inherited in an autosomal dominant manner, [cite journal |pmid=6484975 |year=1984 |month=Jul |author=Mori, K; Suzuki, S; Sugai, K |title=Electron microscopic and functional studies on platelets in gray platelet syndrome |volume=143 |issue=3 |pages=261–87 |issn=0040-8727 |journal=The Tohoku journal of experimental medicine |url= |format=Free full text] although a few autosomal recessive cases have been noted.
