Confirmatory report identifies a pathogenic variant in CSF3 linked to severe congenital neutropenia, suggesting a genetic basis.
Severe congenital neutropenia (SCN) is a genetically heterogeneous condition. Reaching a molecular diagnosis is important for management, prognostication, and risk assessment. We present the first confirmatory report of a previously proposed SCN due to a homozygous pathogenic loss-of-function variant in CSF3. Our report supports this new gene-disease relationship in humans.
