00392294 CMS2401 - - M no (United States) white 0 0 - - epilepsy, X-linked, with variable learning disabilities and behavior disorders Pathogenic variants in the Oligophrenin 1 gene (OPHN1) cause an X-linked intellectual disability syndrome with a phenotype typically consisting of cerebellar hypoplasia, ventriculomegaly, seizures, facial dysmorphism, speech delay and sometimes behavioral difficulties. We describe a male patient with global developmental delay, and cerebellar hypoplasia and other neuroanatomical findings suggestive of a Dandy-Walker malformation. The clinical pontocerebellar hypoplasia sequencing panel revealed a partial duplication from exon 7 to exon 15 in OPHN1, which was maternally inherited. PCR-Sanger sequencing of cDNA showed a truncating frameshift in the OPHN1 transcript. Further, transcript level analysis of OPHN1 showed a 75% reduction in the total expression in the patient in comparison to controls. Presumably this leads to a similar reduction in the level of OPHN1 protein resulting in the observed phenotype. This is the first report of a partial duplication of exons 7-15 in OPHN1 in a patient with strabismus, speech delay, dysmorphic facial features, epilepsy, an autism-like phenotype, and developmental delay. 1 1 Dr. Laxmi Kirola
