Urofacial syndrome (UFS) (or Ochoa syndrome) is an autosomal-recessive disease characterized by congenital urinary bladder dysfunction, associated with a significant risk of kidney failure, and an abnormal facial expression upon smiling, laughing, and crying.
- Rare variants in LRIG2 might be relevant to nonsyndromic bladder disease.
- UFS is also caused by mutations in HPSE2, encoding heparanase-2.
- LRIG2 and heparanase-2 are immunodetected in nerve fascicles growing between muscle bundles within the human fetal bladder, directly implicating both molecules in neural development in the lower urinary tract.
