He presented at age 2 years with problems with walking. These included a waddling gait and a right sided limp, such that he could no longer run with his peers. Over time, the condition progressed to the point that he had difficulties to raise from a chair and was unable to stand from a sitting position on the ground. His father noticed that he could not get up from his bed unassisted. His cognition, vision, language and hearing are entirely normal. His prenatal and newborn history were normal. There is a positive family of siblings with similar findings.
