X small rings
MONDO:0019926X small rings is a rare chromosome X structural anomaly, with highly variable phenotype, principally characterized by developmental delay, intellectual disability, short stature, craniofacial dysmorphism (incl. microcephaly, facial asymmetry, hypertelorism, long palpebral fissures, epicanthus, low-set or malrotated ears, broad nose with a flat nasal bridge, anteverted nares, long philtrum, thin upper lip, high arched palate, micrognathia) and skeletal anomalies (e.g. cubitus valgus, talipes equinovarus). Patients may also present heart malformations (e.g. ventricular septal defects, mitral valve stenosis), sacral dimple, soft tissue syndactyly, pigmented nevi, and seizures.

Scientists probe genetic secrets of lost fetuses to unravel sex chromosome mysteries
Knowledge-focused By invitation onlyThis study looks at fetuses with sex chromosome disorders (like extra or missing X or Y chromosomes) that were either miscarried or electively aborted. Researchers will analyze the placenta and fetal tissues to see how the chromosome changes affect gene activity and development. …
