Observed at very low frequency in gnomAD.

Structural Context

Position 216 at pLDDT 41 — DEEP IDR. Sparse neighbors (GLY217, GLN215, ALA214). DynaMut2 untrustworthy.

P216R introduces charge + removes backbone constraint in disordered region. AM 0.11 under-call; multi-phenotype confirms clinical pathogenicity.

Amino-acid chemistry
Proline (P) → Arginine (R) — rigid helix-breaking replaced by long positively-charged amine.
Position in the protein
N-terminal cytoplasmic domain · position 216 IDR (pLDDT 41 — deep IDR).

Druggability Assessment

Category 5 — IDR Exclusion. pLDDT 41 deep IDR. AlphaMissense 0.11 below threshold. DynaMut2 prediction not trustworthy.

The Atlas routes Category 5 variants to wet-lab characterization. Multi-phenotype confirms clinical pathogenicity.

Why this matters

P216R is another deep-IDR variant in this batch — Atlas appropriately flags for wet-lab.
