Genes affected

NBEAL2 (HGNC:31928): (neurobeachin like 2) The protein encoded by this gene contains a beige and Chediak-Higashi (BEACH) domain and multiple WD40 domains, and may play a role in megakaryocyte alpha-granule biogenesis. Mutations in this gene are a cause of gray platelet syndrome. [provided by RefSeq, Dec 2011]

NBEAL2 Gene-Disease associations (from GenCC):

• gray platelet syndrome
