Curated reports relevant to this gene

  • Inherited Platelet Function Disorders

    • RASGRP2-Related Platelet Disorder (Platelet-Type Bleeding Disorder 18)Autosomal recessive

      A recessive disorder caused by changes in RASGRP2 that impairs platelet activation, causing bleeding from the gums and nose and after injury.

      • ClinGen rates the link definitive
      • 4 GenCC submitters rate it definitive or strong
      What knowing changes

      Knowing about it helps plan bleeding prevention around surgery, dental work and childbirth, and avoid medicines that affect platelet function.

  • Osteopetrosis

    • Osteopetrosis, also known as marble bone disease, is a descriptive term that refers to a group of rare, heritable disorders of the skeleton characterized by increased bone density on radiographs.

      • 1 GenCC submitter rates it definitive or strong

Inheritance

Autosomal recessive
It takes a changed copy from each parent. With one, you are a carrier and usually unaffected; when both parents are carriers, each child has a one-in-four chance of inheriting two.
