Silver-Russell syndrome due to maternal uniparental disomy of chromosome 7 is a genetic malformation syndrome with short stature characterized by severe prenatal and postnatal growth retardation, feeding difficulties, body asymmetry, dysmorphic craniofacial features (triangular-shaped face, relative macrocephaly, frontal bossing, micrognathia, down-turned corners of the mouth) and other anomalies (fifth finger clinodactyly, café au lait macules, male genital anomalies, mild developmental delay and/or speech delay with movement disorders).
Features include very common findings: Micrognathia, Intrauterine growth retardation, Delayed skeletal maturation, and Postnatal growth retardation; and common findings: Thin vermilion border, Triangular face, Abnormality of the outer ear, and Delayed speech and language development and others. 59 total HPO annotations.
