Abnormal expression of imprinted genes leads to imprinting disorders (IDs). Silver-Russell syndrome (SRS) and Prader-Willi syndrome (PWS) are representative IDs showing small for gestational age and short stature (SGA-SS).Temple syndrome (TS14) caused by abnormal gene expression at the 14q32.2 imprinted region, maternal uniparental disomy of chromosome 6 (UPD(6)mat), 16 (UPD(16)mat), and 20 (UPD(20)mat) are also associated with SGA-SS. Fuethermore, some copy number variations ...
