In addition to hyperpigmented skin the patient exhibited sectorial heterochromia iridis. Sequence analysis of the steroidogenic acute regulatory protein (<jats:italic>StAR<\/jats:italic>) gene showed a novel homozygous mutation (c.652G\u2009&gt;\u2009A (p.Ala218Thr), which was predicted <jats:italic>in-silico<\/jats:italic> to be possibly damaging. Under daily steroid substitution her electrolyte levels are balanced while she became obese. Puberty occurred spontaneously.<\/jats:p>\n              <\/jats:sec>\n              <jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>A novel mutation in the <jats:italic>StAR<\/jats:italic> gene was identified in a patient with severe adrenal hypoplasia and sectorial heterochromia iridis. We discuss a causal relationship between these two rare phenotypes, i.e. whether very high levels of ACTH and alpha-MSH during early development might have disturbed early differentiation and distribution of uveal melanocytes. If confirmed in additional cases, discolorization of the iris might be considered as an additional phenotypical feature in the differential diagnosis of congenital adrenal insufficiency.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12902-019-0448-2","type":"journal-article","created":{"date-parts":[[2019,10,30]],"date-time":"2019-10-30T20:44:43Z","timestamp":1572468283000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A novel mutation of the StAR gene with congenital adrenal hyperplasia and its association with heterochromia iridis: a case report"],"prefix":"10.1186","volume":"19","author":[{"given":"Vera","family":"Splittst\u00f6sser","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felix","family":"Schreiner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bettina","family":"Gohlke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maik","family":"Welzel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul-Martin","family":"Holterhus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joachim","family":"Woelfle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2019,10,30]]},"reference":[{"key":"448_CR1","doi-asserted-by":"publisher","first-page":"1828","DOI":"10.1126\/science.7892608","volume":"267","author":"D Lin","year":"1995","unstructured":"Lin D, Sugawara T, Strauss JF 3rd, Clark BJ, Stocco DM, Saenger P, Rogol A, Miller WL.
