Weiss-Kruszka syndrome is a recently described genetic disorder characterized by craniofacial features, ptosis, dysgenesis of the corpus callosum, and neurodevelopmental impairment.

Here we report the first case of Weiss-Kruszka syndrome, associated to a de novo 9q31.1q31.3 microdeletion showing an acute lymphoblastic leukemia.A speculation on the contribution of our case to the phenotypic expansion of WSKA is here discussed.

Abstract

Weiss-Kruszka syndrome is a recently described genetic disorder characterized by craniofacial features, ptosis, dysgenesis of the corpus callosum, and neurodevelopmental impairment. It is caused by heterozygous loss-of-function variantsin ZNF462 gene.During the time, the original phenotype was expanded, including several complications, sensorineural hearing loss, congenital hypogonadotropic hypogonadism with anosmia and complete growth hormone deficiency associated with empty sella syndrome. Here we report the first case of Weiss-Kruszka syndrome, associated to a de novo 9q31.1q31.3 microdeletion showing an acute lymphoblastic leukemia.A speculation on the contribution of our case to the phenotypic expansion of WSKA is here discussed. More clinical and functional studies are needed to elucidate this association. A possible expansion of the WSKA phenotype is discussed.
