Genotype of PAX2-related disorders correlates with kidney and ocular manifestations.

ABSTRACT: PAX2-related disorders encompass renal coloboma syndrome (RCS) and hereditary focal segmental glomerulosclerosis (FSGS) type 7. We retrospectively analyzed 27 Korean patients with PAX2 pathogenic variants detected between 2004 and 2022 and conducted a literature review of 328 cases, including 301 previously reported. In our cohort, 19 had RCS, 4 had FSGS, and 4 had isolated congenital anomalies of the kidneys and urinary tract. Patients were classified by variant type into predicted loss of function (pLoF) and non-pLoF variant groups, and by variant location into paired domain and other sites group. pLoF variants were predominantly associated with RCS, observed in 82% of patients in both our data (18 of 22, P = 0.017) and the literature (140 of 171, P < 0.001).
