Is ELANE p.Pro234Leu (c.701C>T) pathogenic?

ELANE p.Pro234Leu (c.701C>T) is classified Uncertain significance in ELANE (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-11-12). AlphaMissense: ambiguous (0.4559); Rare (popmax 0.132%, mid); Associated with cyclic neutropenia.

What condition is associated with ELANE p.Pro234Leu (c.701C>T)?

ELANE p.Pro234Leu (c.701C>T) is associated with cyclic neutropenia, neutropenia, severe congenital, 1, autosomal dominant (ClinVar).

How common is ELANE p.Pro234Leu (c.701C>T) in the general population?

ELANE p.Pro234Leu (c.701C>T) is rare (popmax 0.132%, mid) (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.Pro234Leu (c.701C>T)?

AlphaMissense predicts ambiguous (score 0.4559) — an in-silico prediction, not a clinical call.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
