Proteinuric renal disease
Gene: NOS1AP
Comment on list classification: As reviewed by Zornitza Stark and reported in PMID:33523862, there are two unrelated individuals with homozygous NOS1AP variants (c.428G>A/ p.Cys143Tyr & c.345-3T-G) and presenting with nephrotic syndrome, type 22 (MIM# 619155).
Introduction of patient variant (c.428G>A) has resulted in aberrant glomeruli formation in kidney organoids. In addition, homozygous exon 3-deleted mice recapitulated the human phenotype, exhibiting proteinuria, foot process effacement, and glomerulosclerosis.
Hence, there is sufficient evidence available for the promotion of this gene to green rating in the next GMS review.Created: 24 Jan 2024, 7:58 p.m. | Last Modified: 24 Jan 2024, 7:58 p.m.

Nephrotic syndrome type 22 (NPHS22) is an autosomal recessive renal disease characterized by onset of progressive kidney dysfunction in infancy. Affected individuals usually present with edema associated with hypoproteinemia, proteinuria, and microscopic hematuria. Renal biopsy shows effacement of the podocyte foot processes, glomerulosclerosis, and thickening of the glomerular basement membrane. The disease is steroid-resistant and progressive, resulting in end-stage renal disease usually necessitating kidney transplant. Two unrelated families and animal model.
