Is ELANE p.Arg91Pro (c.272G>C) pathogenic?

ELANE p.Arg91Pro (c.272G>C) is classified Uncertain significance in ELANE (ClinVar, Single submitter, 1 submitter; last evaluated 2022-09-26). AlphaMissense: ambiguous (0.434); Very rare (popmax 8.48e-05%, nfe); Associated with cyclic neutropenia.

What condition is associated with ELANE p.Arg91Pro (c.272G>C)?

ELANE p.Arg91Pro (c.272G>C) is associated with cyclic neutropenia, neutropenia, severe congenital, 1, autosomal dominant (ClinVar).

How common is ELANE p.Arg91Pro (c.272G>C) in the general population?

ELANE p.Arg91Pro (c.272G>C) is very rare (popmax 8.48e-05%, nfe) (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.Arg91Pro (c.272G>C)?

AlphaMissense predicts ambiguous (score 0.434) — 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.
