Prenatally detected interstitial deletion 13q12.3–q22 in a fetus with a cystic hygroma

Prenatally detected cases of 13q-syndrome are infrequently reported, especially those with proximal deletion 13q. To the best of our knowledge, case 2 presented by Tosca et al. (2011) in the article discussing genotype–phenotype correlation in patients with interstitial deletion 13q13.3 to 13q21.3, and the report of Miyake et al. (2008) on del(13)(q21.1q22.3) found in the fetus with a duodenal atresia are the only two reports on the prenatally diagnosed cases with interstitial deletion of 13q proximal segments. Herein, we present a case of del(13)(q12.3q22) in a fetus with a septated cystic hygroma, prenatally ascertained after chorionic villus sampling.
