A case of a young girl with Myelodysplastic Syndrome (MDS), dysmorphic features, short stature, and developmental delay – Is there a link?

Abstract

Myelodysplastic Syndrome (MDS) is a problem of ineffective hematopoesis, due to a clonal disorder of the hematopoetic stem cells. MDS is rare in children and considered premalignant as it often progresses to leukemia over time. There are known inherited predisposing conditions to MDS that have been reported in the literature. We describe the case of a 12-year-old girl with multiple dysmorphic features, short stature, and developmental delay with a new diagnosis of MDS (RAEB) with no confirmed genetic diagnosis linking all these features together. We propose that her underlying syndromic diagnosis may have predisposed her to MDS.
