Background: Heterozygous de novo variants in SAMD9 cause the complex multisystem growth disorder, MIRAGE syndrome. Core features are myelodysplasia, infection, restricted growth, adrenal hypoplasia, genital/gonadal phenotypes, and enteropathy. However, the range of additional associations is expanding and includes disrupted placental development, poor post-natal growth, and other endocrine features. Milder phenotypes are also described, such ...

Background: Recurrent miscarriage (RM) is traditionally described as three or more consecutive pregnancy losses and remains a challenging condition, affecting 1-3% of couples trying to conceive. Although factors such as uterine abnormalities, maternal hypothyroidism and parental balanced translocations are associated with RM, in most situations the aetiology is unknown. The coexistence of RM and live births in many families suggests a potential association wit...

Introduction: Our Centre is an international referral centre for genetic analysis of children with short stature (SS) and features of GH/IGF-1 resistance. Following candidate gene and whole exome sequencing, diagnoses for ~50% patients remained elusive. Copy number variation (CNV) has not previously been investigated in GH/IGF-1 resistance and we hypothesised that CNVs contribute to the phenotype in our undiagnosed cohort.Experimental Design and Methodol...

Background: Monosomy × (45,X) is associated with Turner syndrome (TS) and pregnancy loss; however, the underlying mechanisms remain unclear. Girls and young women with TS/45,X can present with diverse clinical features and at different ages, including early postnatal life, suggesting that at least some mechanisms may be defined during early fetal development.Aims: To explore transcriptomic expression profiles in ke...
