| Remarks |
Clinically affected; symptom onset began at 3 months; mother noted decreased movement towards end of pregnancy; mother was on enoxaparin during pregnancy; at 3 months of age, MRI showed multiple lesions including pontocerebellar hyperplasia, asgenesis of corpus callosum, and decreased myelination, failure to thrive; facial dysmorphism; symptoms include seizures, brain abnormalities including agenesis of the corpus callosum, cataracts, optic atrophy, chronic lung disease, mild hypertrophic cardiomyopathy, severe myopathy/hypotonia, GI dysmotility with G-tube, multiple pneumonias, urosepsis, obstructive sleep apnea, unable to follow verbal commands (this milestone has since been achieved); normal karyotype, WES GeneDx; genetic testing revealed a homozygous recessive mutation in the EPG5 gene: c.1007A>G (p.Q336R); treatments: G-tube, Nissan fundoplication, physical therapy, speech therapy, occupational therapy; assisted devices: wheelchair, orthotics, communication/learning device; no family history of the disease; parents are non-consanguineous; PubMed ID# 26917586, 27343256, 27343258; same subject as GM26249 (lymph)and GM27291 (stem cell); unaffected carrier mother is GM26251 (Lymph); unaffected carrier father is GM26250 (Lymph) and GM27894 (fibro); unaffected sister is GM27895 (fibro). |
