A 17q21.31 microduplication, reciprocal to the newly described 17q21.31 microdeletion, in a girl with severe psychomotor developmental delay and dysmorphic craniofacial features.

Abstract excerpt

Array-CGH analysis using 244k Agilent oligoarray revealed a de novo 17q21.31 microduplication in a 10-year-old girl with severe psychomotor developmental delay, facial dysmorphism, microcephaly, abnormal digits and hirsutism. The duplication encompassed the MAPT and CRHR1 genes and was reciprocal to the recently described 17q21.31 microdeletion, associated with a recognizable clinical phenotype. Genotyping showed...
