Added comment: The thrombocytopenia-absent radius syndrome (TAR) is characterised by reduction in the number of platelets and absence of the radius; preservation of the thumb distinguishes TAR from other syndromes that combine blood abnormalities with absence of the radius, such as Fanconi anemia. Individuals with TAR have low numbers of megakaryocytes, platelet precursor cells that reside in bone marrow, and frequently present with bleeding episodes in the first year of life that diminish in frequency and severity with age. The severity of skeletal anomalies varies from absence of radii to virtual absence of upper limbs, with or without lower limb defects such as malformations of the hip and knee.

Vast majority of cases include a recurrent 200kb deletion on one allele (although truncations are seen) and the presence of 1 of 2 SNPs in trans. The SNPs have a MAF of 3.05% and 0.42%. Cases have been reported with this phenotype without the 200kb deletion (PMID: 22366785, 32227665).

Currently, the large CNV in majority of cases would not be detected.
