Abstract

<i>SGMS2</i> mutation can present with childhood-onset low bone mass and recurrent fragility fractures. We report a 25-year-old man with a three-generation family history of recurrent fragility fractures and diffuse high bone mass. He was found to have a heterozygous frameshift variant c.1052_1074dup in the SGMS2 gene. Our case highlights a novel genetic mutation in the <i>SGMS2</i> gene and reports the first family of <i>SGMS2</i> mutation with high bone mass.
