      Case: M, 22Y0M, Caucasian

      FamilyInfo: Positive family history.

      CohortInfo: Case series of 14 patients with definite or presumed von Hippel-Lindau disease and retinal vascular proliferation.

      CaseHPOFreeText: At age 12, his left eye had a large juxtapapillary vascular complex extending from the nerve along the superior arcade that was associated with dense fibrovascular tissue. During the next 29 months, this fibrovascular complex enlarged, extending into the center of the macula and causing a decrease in visual acuity to 20/80. The patient underwent pars plana vitrectomy and membrane peel. When the patient was reexamined 7 years after his surgery, there was no recurrence of the lesion. In the patient's contralateral right eye, 3 typical peripheral RCHs were observed during this 7-year follow-up. At age 14 years, he was also noted to have a small patch of superficial retinal vessels in the inferior retinal quadrant near the equator of the right eye that resembled an arteriovenous anastomosis.

      CaseHPOFreeText:Patient 7 presents with severe intellectual disability, developmental slowdown, and various seizure types. Patient 7 has Autistic Spectrum Disorder (ASD) and microcephaly.

      Patient History

      @ 12 months - Patient 7 presented with seizures.

      Patient 7 developed additional seizure types including: focal seizures with/without generalization, generalized tonic/clonic/tonic-clonic seizures, myoclonic seizures, and hypomotor seizures.

      Patient 7 was on two antiepileptic drugs at most recent followup visit which reduced seizure frequency by >50%.

      CasePreviousTesting:The authors selected a cohort of 31 patients with seizure cryptogenic Neonatal/Infantile Epileptic Encephalopathy (NIEE) and seizure onset before 24 months.

      Exclusion criteria included: (1) Patients with a definite history of brain insult, malformation of cortical development, neurocutaneous and syndromal disorders, and confirmed or highly suspected neurometabolic disorders based on clinical and biochemical markers. (2) Patients with Dravet syndrome and epilepsy at infancy with migrating focal seizure were also excluded because the majority of variants are detected in the SCN1A (>85%) and KCNT1 (approximately 50%) genes.

      Formal neuropsychological testing or best clinical assessment was used to classify patient development or intelligence.

      PreviouslyPublished:Not previously published

      GenotypingMethod:Whole Exome Sequencing (WES) variant results were filtered in a panel of 430 epilepsy-associated genes. After selection of variants from the 430-gene panel, the synonymous variants, variants with variant frequency <10%, and variants with allele frequency >1% were removed.

      Gene:SLC9A6

      Variant:Hemizygous splice site NM_001042537.1 c. 794-2A>G was assessed by the authors to be likely pathogenic.
