Renal dysfunction in sibs with band like calcification with simplified gyration and polymicrogyria: Report of a new mutation and review of literature

Band like calcification with simplified gyration and polymicrogyria (BLC-PMG) is a distinct neuroradiological phenotype initially reported as a pseudo-TORCH syndrome and known to result from biallelic mutations in the Occludin(OCLN) gene. This is report of a family of Indian origin with two affected sibs and segregation of a homozygous novel OCLN mutation in the exon 3(NG_028291.1(OCLN_v001): c.252delC). A literature review suggests that renal dysfunction may be an unrecognized phenotypic manifestation of OCLN mutations and monitoring for the same should form part of the clinical care of these individuals.
