Molecular genetic characterization of a prenatally detected de novo interstitial deletion of chromosome 2q (2q31.1-q32.1) encompassing HOXD13, ZNF385B and ZNF804A associated with syndactyly and increased first-trimester nuchal translucency

Fetuses with an interstitial deletion of 2q31.1-q32.1 may be associated with increased first-trimester NT. Haploinsufficiency of HOXD13 is associated with syndactyly. Genomic microarray is useful in detecting subtle chromosomal abnormalities in fetuses with increased NT and normal karyotype.
