Inherited thrombocytopenias (ITs) are a heterogeneous group of syndromic and nonsyndromic diseases caused by mutations affecting different genes. Alterations of ACTN1, the gene encoding for α-actinin 1, have recently been identified in a few families as being responsible for a mild form of IT (ACTN1-related thrombocytopenia; ACTN1-RT). To better(More)
We report the case of a child with clinical and haematological features indicative of juvenile myelomonocytic leukaemia (JMML). The patient showed dysmorphic features: high forehead, bilateral epicanthal folds, long eyebrows, low nasal bridge and slightly low-set ears. A 38G>A (G13D) mutation in exon 1 of the NRAS gene was first demonstrated on peripheral(More)
Abnormalities of platelet size are one of the distinguishing features of inherited thrombocytopenias (ITs), and evaluation of blood films is recommended as an essential step for differential diagnosis of these disorders. Nevertheless, what we presently know about this subject is derived mainly from anecdotal evidence. To improve knowledge in this field, we(More)
BACKGROUND Single nucleotide polymorphisms (SNPs) in platelet-associated genes partly explain inherent variability in platelet counts. Patients with monoallelic Bernard Soulier syndrome due to the Bolzano mutation (GPIBA A156V) have variable platelet counts despite a common mutation for unknown reasons. OBJECTIVES We investigated the effect of the most(More)
A twin pair affected by juvenile myelomonocytic leukemia (JMML) with the same somatic PTPN11 mutation and abnormal chromosome 7 in bone marrow samples but distinct prognostic gene expression signatures, received a matched-unrelated donor and matched-unrelated cord blood transplant, respectively. Both twins fully engrafted, but after 6 months, the twin with(More)

Juvenile myelomonocytic leukemia (JMML) is a rare myelodysplastic/myeloproliferative disorder of early childhood characterized by mutations of the RAS-RAF-MAP kinase signaling pathway. We report the case of a child with a diagnosis of JMML carrying two mutations of NRAS gene (c.37G>C and c.38G>A) independently occurring in long-term culture initiating(More)
Familiar aggregation of breast cancer has been known since Roman times, but it has been discussed in practical terms only from the 19th century. Most of the studies dealing with this issue suggest that the risk is higher in relatives of patients with early onset and that the risk also increases as a function of the bilaterality of the disease or the(More)
