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.

Patient History

@ 3 months - Patient 1 had microcephaly (head circumference was less than 3rd percentile with a body weight and body height at 75th percentile). Patient 1 had hypotonia.

Patient 1 was given a metabolic screening, a muscle enzyme, and a brain tomography with normal results.

Patient history

@ birth - Patient 1 was born at 38 weeks of gestation after an uncomplicated pregnancy. Her weight was 3,390 g (P69), height 51 cm (P60), and her head circumference was 36 cm (P90).

@ 6 months - Patient 1 experienced developmental delay.

@ 9 months - Patient 1 sat without support.

@ 2 years - Patient 1 began to walk.

@ later on - Patient 1 presented with speech delay and behavioral disturbances. The behavioral disturbances were reduced by the drug risperidone.

@ early childhood - Patient 1 has been obese and appeared to display hyperphagia.

@ 8 years - Patient 1 developed precocious puberty.

@ 10 years - Patient 1 had her first epileptic seizure. Treatment with lamotrigine prevented further seizures. The seizures later became refractory to this treatment.

@ 10 years - Patient 1 presented with a height of 160 cm (P>97) and a head circumference of 59 cm (P>97). She had hypertelorism and prominent eyebrows. Her nasal bridge was broad and auricles were fleshy. In addition, Patient 1's neck was short and the fingers were short and wide.

Patient 1 has an intellectual disability, metabolic syndrome, and macrocephaly.

CaseNotHPOs:HP:0002540.

CaseNotHPOFreeText:Patient 1 sat without support at 9 months old. She walked at 2 years.

CasePreviousTesting:Patient 1 was given a conventional cytogenetic analysis. The chromosomal analyses (46,XX) and array CGH results (BlueGnome CytoChip ISCA 4×180K v1.0; Agilent Human Genome CGH Microarray 180K) were normal. Patient 1 was also given a methylation-specific MLPA to exclude a Temple syndrome, which is also characterized by weight gain and precocious puberty. In addition, Prader-Willi syndrome was ruled out by methylation testing. This syndrome is another imprinting disease causing obesity and intellectual disability.

PreviouslyPublished:Not previously published

GenotypingMethod:Whole-exome sequencing analysis of the entire exome was conducted for Patient 1. Whole-genome sequencing showed heterozygosity in Patient 1, which was confirmed by Sanger sequencing.

CaseHPOFreeText:

Patient history

@ 2 months to 2.5 years - Patient 2 experienced tonic and focal seizures with autonomic symptoms.

@ 2 years - Patient 2 was diagnosed with CDKL5 disorder.

Patient 2 had severe delayed gross motor development, severe delayed fine motor development, severe delayed language development and delayed social development. Patient 2 had hyperoral and hand flapping stereotypies. She also had microcephaly (< 2 SD) and axial hypotonia.

Patient 2 was given a brain EEG which detected Delta slowing of the background followed by generalized attenuation during seizures and multifocal interictal epileptiform abnormalities.

@ 2.5 years - Patient 2 experienced seizures in clusters.

Treatments

Antiepleptic treatments included:Phenobarbital, Topirimate, Clobazam, Valproate, Keppra, Vitamin B6, Phenytoin, Lamotrigine, Nitrazepam, Oxcarbazepine, Mirtazipine, KCI, Levetiracetam, ant ketogenic diet.

Patient 2 was also treated with Carnitine. Patient 2's seizures seem to have changed in type over time but continued.

Other testing

Tests were conducted on Patient 2 to obtain data in the following areas: NBS, lactate, lipoprotein profile, plasma and urine amino acids, urine organic acids, acylcarnitine profile, total and free serum carnitine levels, plasma ammonia, total plasma homocysteine, serum CK, liver enzymes, urine alpha-AASA, creatine, biotinidase, VLCFA, Batten disease screen, CSF analysis (amino acids, lactate, glucose, protein, cell count, neurotransmitters), MRI-brain with spectroscopy, and karyotype.

CasePreviousTesting:Patient 2 was given a gene sequence test for the genes SCNIA and MECP2. No gene mutation was found for these two genes.

PreviouslyPublished:Not previously published

GenotypingMethod:Patient 2 was given a CDKL5 gene sequence test. The test detected a mutation in the CDKL5 gene.

Gene:CDKL5

Variant:c. 2480_2486dupCAGATCT. frameshift

The authors state that CDKL5 gene sequencing detected a de novo duplication in exon 17, c. 2480_2486dupCAGATCT, resulting in a frameshift (Boston University School of Medicine, Center for Human Genetics, Boston, MA). This is a novel change that has not been reported before in ExAC. Only pathogenic point mutations in exon 17 have previously been reported. In a patient with a previously reported frameshift mutation in exon 18, a truncated CDKL5 transcript was detected. A truncated protein would lack the C-terminus and would not localize correctly in the cell, as demonstrated in vitro. Accordingly, any reading frame altering mutations proximal to exon 18 are null-variants. Therefore, this mutation is classified as pathogenic according to ACMG criteria.
