Dyschromatosis symmetrica hereditaria: A clue to early diagnosis of Aicardi–Goutières syndrome

Abstract

AbstractA 6‐year‐old female with a history of Aicardi–Goutières syndrome (AGS) presented to dermatology clinic with hypopigmented and hyperpigmented macules and patches consistent with dyschromatosis symmetrica hereditaria (DSH). Previous genetic workup demonstrated a de novo, heterozygous mutation in the adenosine deaminase acting on RNA 1 (ADAR) gene. While the co‐occurrence of AGS and DSH has previously been described in mutations of the ADAR gene, our case highlights the potential association between these disorders that may aid in earlier future diagnosis of AGS.
