Microcephalic Osteodysplastic Primordial Dwarfism in Two Siblings Living in Sindh, Pakistan: A Case Report.

Microcephalic osteodysplastic primordial dwarfism type 2 (MOPD2) is a rare autosomal recessive disorder that presents as a myriad of skeletal abnormalities collectively termed as osteodysplasia, which have their onset during intrauterine life with the fetus exhibiting intrauterine growth restriction. Affected individuals also tend to have a very small head size that is more than three standard deviations (SD) below the mean for a population termed microcephalic. The growth problems progress postnatally, causing stunted growth or short stature. In this report, we present the case of two siblings: a 15-year-old unvaccinated female weighing 8 kg (case one), and a seven-year-old unvaccinated female weighing 6 kg (case two), who presented to the Department of Pediatrics, Unit 2 at the Civil Hospital in Karachi, Pakistan, complaining of short stature since birth.
