A rare constitutional aplastic anaemia characterised by aplastic anaemia, intellectual disability, short stature, and microcephaly. Skin pigmentation or cafe au lait spots are often present. Majority of the patients present global developmental delay with impaired motor skills, learning disabilities, speech delay whereas some patients also may have behavioural problems including autistic features. Patients often develop premalignant myelodysplastic syndromes or leukaemia.	Interprets	True	Platelet count	Inferred relationship	Some	8

A rare unclassified autoinflammatory syndrome characterised by neonatal onset pancytopenia, type I interferon-dependent multisystemic autoinflammation, painful rash with variable frequencies and haemophagocytic lymphohistiocytosis. Failure to thrive, fever, gastrointestinal/upper respiratory tract infections, enterocolitis, hepatosplenomegaly, myelofibrosis and neurodevelopmental delay are other common clinical features. Facial dysmorphism including macrocephaly, mild frontal bossing, sparse hair, mild hypertelorism, depressed nasal bridge can be present.	Interprets	True	Platelet count	Inferred relationship	Some	5
