The 22q11.2 distal deletion syndrome appears to be a recurrent genomic disorder distinct from DiGeorge syndrome and velocardiofacial syndrome, although they share some characteristic features with widely variable expressivity. The common clinical features include prematurity, prenatal and postnatal growth delay, developmental delay, characteristic dysmorphic facial features including smooth philtrum and ear abnormalities, microcephaly, and mild skeletal abnormalities. Cardiac defects are primarily septal defects (Burnside RD, Cytogenet Genome Res. 2015;146(2):89-99. PMID: 26278718). The MAPK1 gene, which is located within the deleted region, may be associated with placental development and low birth weight (Ben-Shachar et al., Am J Hum Genet. 2008 Jan 10; 82(1): 214-221.
