Abstract:Meire-Gorlin syndrome (MGS) is a rare autosomal recessive disorder characterized by a triad of short stature, microtia, and absent or hypoplastic patella. We report a 5-year-old male affected with the subtype MGS1, secondary to c.c2292t mutation of ORC1 gene. Our patient''s features included a triangular face, micrognathia, and delayed motor development. To the edge of our knowledge, this is the first diagnosed Iranian MGS patient and sixth case in the middle east. MGS1 subtype has never shown improvement to growth hormone therapy, therefore underlying molecular defect was suggested to be responsible for patients’ short stature rather than growth hormone deficiency. However, our patients’ growth velocity was improved by growth hormone. We recommend more studies to specify the role of ORC1 gene in this syndrome. In addition, this case report describes the prenatal investigations and sonographic examinations of MGS1 for the first time.
