  Three clinical variants based on age of onset for end stage renal disease (ESRD): infantile: before 2 years of age juvenile (a.k.a. nephronophthisis): most common form, age of onset 10 adolescent (a.k.a. medullary cystic kidney disease): usually develops [radiopaedia.org]

• Pendular Nystagmus

  Ocular examination revealed enophthalmos OU, poor light perception, intraocular pressure of 15 mmHg, sluggish direct and consensual pupillary responses, photophobia, and pendular nystagmus. [healio.com]

Genetic analysis is highly indicated in order to identify causative mutations, assist with further syndromatic workup and help with prognosis. [renalandurologynews.com]

• Ketonuria

  There was normal urinalysis, no hematuria, no glycosuria, no ketonuria, normal excretion of protein in 24-hour urine specimen, low urinary specific gravity, and normal urine cultures. [healio.com]

• Microcytic Anemia

  Laboratory Findings Hemogram showed a moderate hypochromic, microcytic anemia, and eosinophilia (reverted to normal after treatment of ascaris and Trichuris trichiura). [healio.com]

The treatment reduced cyst enlargement, and the early treatment inhibited development of renal fibrosis. Although the effect of later treatment was more modest, both stages of the disease responded positively to treatment. [ncbi.nlm.nih.gov]
