A case of 8q22.1 microdeletion without the Nablus mask-like facial syndrome phenotype.

Nablus mask-like facial syndrome (NMLFS) has been reported in six patients with a recognizable facial appearance, along with other clinical features. Microdeletions of 8q21.3-8q22.1 were identified in all six cases, with the deleted region in common being 8q22.1 (2.78 Mb in length). In this report, we describe a child with speech delay and features of an autistic spectrum disorder and with a 1.6 Mb deletion of 8q22.1. The deletion has significant chromosomal overlap with previously reported examples of NMLFS, but our patient lacks the clinical features noted in the published cases.
