Abstract excerpt
Germline gain-of-function variants in sterile alpha motif domain-containing 9-like (SAMD9L), located on chromosome 7q, cause a multisystem disorder characterized by bone marrow failure, immunodeficiency and variable neurological involvement. Disease evolution is frequently shaped by somatic genetic rescue (SGR), most commonly through monosomy 7, somatic loss-of-function (LOF) variants in cis or uniparental disomy...
