LHX4 mutations are rare in combined pituitary hormone deficiency, and even rarer in isolated GHD. We describe a 14 years old boy who was referred for investigation of short stature. Convergent strabismus, nystagmus was present. At the age of 5 years his gait was unstable. A progressive myopathy ensued. Tests of pituitary reserve showed partial IGHD (8.2 ng/ml). Other pituitary hormones were within normal range. Muscle biopsy showed congenital myopathy of undefined etiology. MRI of the brain revealed the empty sella syndrome. Targeted resequencing with a panel containing probe sets for enrichment and analysis of > 4,800 clinically relevant genes, targeting 12Mb of the human genome revealed the c.250C>T (R84C) LHX4 mutation. His father is healthy, with no myopathy or pituitary deficiencies, but has the same LHX4 mutation. This report extends the range of phenotypes associated with LHX4 gene mutations. To the best of our knowledge, we are the first to report on congenital myopathy in an LHX4 gene mutation. Forthwith, we offer a comprehensive review of the patients published so far with their clinical and genetic characteristics.
