Is ELANE p.Leu206Phe (c.618G>T) pathogenic?

ELANE p.Leu206Phe (c.618G>T) is classified Likely pathogenic in ELANE (ClinVar, Single submitter, 2 submitters; last evaluated 2025-09-23). AlphaMissense: likely pathogenic (0.8023); Absent from gnomAD v4.1; Associated with cyclic neutropenia.

What condition is associated with ELANE p.Leu206Phe (c.618G>T)?

ELANE p.Leu206Phe (c.618G>T) is associated with cyclic neutropenia, neutropenia, severe congenital, 1, autosomal dominant (ClinVar).

How common is ELANE p.Leu206Phe (c.618G>T) in the general population?

ELANE p.Leu206Phe (c.618G>T) is absent from gnomAD v4.1 (gnomAD).

How is Cyclic neutropenia inherited?

Typically Autosomal dominant (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about ELANE p.Leu206Phe (c.618G>T)?

AlphaMissense predicts likely pathogenic (score 0.8023) — an in-silico prediction, not a clinical call.
