PMID 39763161: Two affected fetuses from a family of six relatives carried biallelic variants in MPL. Each parent and two unaffected siblings were carriers of one heterozygous variant. These two variants (p.R102P and p.R537W) have been reported in the context of congenital amegakaryocytic thrombocytopenia, a recessive condition with FICH as one of its manifestations
