Language skills and neuropsychological performance in patients with SHH mutations and a holoprosencephaly-like phenotype

Am J Med Genet A. 2006 Oct 1;140(19):2085-90. doi: 10.1002/ajmg.a.31311.

Abstract

Here, we evaluate linguistic skills and neuropsychological performance in a sample of patients with SHH mutations and a holoprosencephaly (HPE)-like phenotype, a minor form of classic HPE. Our findings suggest that patients with SHH mutations and a HPE-like phenotype have normal cognitive ratios and significant language impairment. Imaging evaluation by magnetic resonance imaging (MRI) was normal in three patients and in one there was hypoplasia of the anterior commissure and the presence of a temporal cyst, apparently not related to the clinical findings.
