ClinGen expert panel — Rett and Angelman-like Disorders VCEP

Benign for FOXG1 disorder. Applied ACMG criteria (verbatim):

BP7 BA1

Curation rationale (ClinGen, verbatim)

The allele frequency of the p.Pro67= variant in FOXG1 is 0.055% in European (Non-Finnish) sub population in gnomAD, which is high enough to be classified as benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BA1). The silent p.Pro67= variant is not predicted to affect splicing using multiple computational tools and does not affect a highly conserved nucleotide (BP7). In summary, the p.Pro67= variant in FOXG1 is classified as benign based on the ACMG/AMP criteria (BA1, BP7).

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.
