The placenta: a site of platelet production?

abstract：:This manuscript reviews pathogenic variants in RASGRP2, which are the cause of a relatively new autosomal recessive and nonsyndromic inherited platelet function disorder, referred to as platelet-type bleeding disorder-18 (BDPLT18)(OMIM:615888). To date, 18 unrelated BDPLT18 pedigrees have been reported, harboring 19 d...
