Schimke immune osseous dysplasia: a rare case report

Vani H. N., Chidananda Gudur, Supriya N., Pragalatha Kumar, Raghupathy P.

Abstract


Schimke immune-osseous dysplasia (SIOD) is primarily characterized by the combination of spondyloepiphyseal dysplasia (SED), unique clinical phenotype, immune complex nephropathy (focal segmental glomerulosclerosis) and progressive immune defects with T-cell immunodeficiency. SIOD is caused by mutations in SMARCAL1 gene. Here we report a case of a 6-year-old girl who presented to us with disproportionate short stature, short neck kyphoscoliosis, hyper pigmented macules and severe herpes zoster. On further evaluation, she had evidence of T cell deficiency and nephrotic range of proteinuria. Renal histopathology documented focal segmental glomerular sclerosis. Genetic analysis confirmed homozygous missense mutation of SMARCAL gene on exon 8 variant c1358G>c. On extensive literature survey, this is noted to be the first case of SIOD reported from India. These children need close surveillance to watch for infections and progressive renal failure and require special care during administration of certain drugs and live vaccines.
