Nephronophthisis- MedGen UID:
- 146912
- •Concept ID:
- C0687120
- •
- Disease or Syndrome
The nephronophthisis (NPH) phenotype is characterized by reduced renal concentrating ability, chronic tubulointerstitial nephritis, cystic renal disease, and progression to end-stage renal disease (ESRD) before age 30 years. Three age-based clinical subtypes are recognized: infantile, juvenile, and adolescent/adult. Infantile NPH can present in utero with oligohydramnios sequence (limb contractures, pulmonary hypoplasia, and facial dysmorphisms) or postnatally with renal manifestations that progress to ESRD before age 3 years. Juvenile NPH, the most prevalent subtype, typically presents with polydipsia and polyuria, growth retardation, chronic iron-resistant anemia, or other findings related to chronic kidney disease (CKD). Hypertension is typically absent due to salt wasting. ESRD develops at a median age of 13 years. Ultrasound findings are increased echogenicity, reduced corticomedullary differentiation, and renal cysts (in 50% of affected individuals). Histologic findings include tubulointerstitial fibrosis, thickened and disrupted tubular basement membrane, sporadic corticomedullary cysts, and normal or reduced kidney size. Adolescent/adult NPH is clinically similar to juvenile NPH, but ESRD develops at a median age of 19 years. Within a subtype, inter- and intrafamilial variability in rate of progression to ESRD is considerable. Approximately 80%-90% of individuals with the NPH phenotype have no extrarenal features (i.e., they have isolated NPH); ~10%-20% have extrarenal manifestations that constitute a recognizable syndrome (e.g., Joubert syndrome, Bardet-Biedl syndrome, Jeune syndrome and related skeletal disorders, Meckel-Gruber syndrome, Senior-Løken syndrome, Leber congenital amaurosis, COACH syndrome, and oculomotor apraxia, Cogan type).
Renal tubular atrophy- MedGen UID:
- 388054
- •Concept ID:
- C1858395
- •
- Finding
The presence of renal tubules with thick redundant basement membranes, or a reduction of greater than 50% in tubular diameter compared to surrounding non-atrophic tubules.
Tubular basement membrane disintegration- MedGen UID:
- 368847
- •Concept ID:
- C1968618
- •
- Finding
DIsruption and breaking up of the basement membrane of the tubules of the kidney.
Renal corticomedullary cysts- MedGen UID:
- 409631
- •Concept ID:
- C1968619
- •
- Disease or Syndrome
The presence of multiple cysts at the border between the renal cortex and medulla.
Tubulointerstitial fibrosis- MedGen UID:
- 370652
- •Concept ID:
- C1969372
- •
- Disease or Syndrome
A progressive detrimental connective tissue deposition (fibrosis) on the kidney parenchyma involving the tubules and interstitial tissue of the kidney. Tubulointerstitial injury in the kidney is complex, involving a number of independent and overlapping cellular and molecular pathways, with renal interstitial fibrosis and tubular atrophy (IF/TA) as the final common pathway. However, IF and TA are separable, as shown by the profound TA in renal artery stenosis, which characteristically has little or no fibrosis (or inflammation). For new annotations it is preferable to annotate to the specific HPO terms for Renal interstitial fibrosis and/or Renal tubular atrophy.
Stage 5 chronic kidney disease- MedGen UID:
