Genes affected

CCDC12 (HGNC:28332): (coiled-coil domain containing 12) Predicted to be part of U2-type spliceosomal complex and post-mRNA release spliceosomal complex. [provided by Alliance of Genome Resources, Apr 2022]

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

  Inheritance: AR, AD Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: ClinGen, Orphanet, Labcorp Genetics (formerly Invitae)
