Silver Russell syndrome in a preterm girl with 8q12.1 deletion encompassing PLAG1

Silver Russell syndrome (SRS) is a congenital disorder characterized by intrauterine growth retardation (IUGR), feeding difficulties and postnatal growth retardation. In a small number of cases, PLAG1 variants have been described (OMIM #618907). PLAG1 haploinsufficiency decreases Insulin-like growth factor 2 expression and produces a Silver Russell syndrome-like phenotype. Here, we describe the phenotype and molecular features of a 26 months girl with clinical features of SRS, and a de novo 2.1 Mb deletion encompassing PLAG1 is reported in association with clinical features suggestive of SRS.
