Is ADAM17 p.Ser770Pro (c.2308T>C) pathogenic?

ADAM17 p.Ser770Pro (c.2308T>C) is classified Uncertain significance in ADAM17 (ClinVar, Single submitter, 1 submitter; last evaluated 2019-09-20). AlphaMissense: likely benign (0.2267); Absent from gnomAD v4.1; Associated with inflammatory skin and bowel disease, neonatal, 1.

What condition is associated with ADAM17 p.Ser770Pro (c.2308T>C)?

ADAM17 p.Ser770Pro (c.2308T>C) is associated with inflammatory skin and bowel disease, neonatal, 1 (ClinVar).

How common is ADAM17 p.Ser770Pro (c.2308T>C) in the general population?

ADAM17 p.Ser770Pro (c.2308T>C) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about ADAM17 p.Ser770Pro (c.2308T>C)?

AlphaMissense predicts likely benign (score 0.2267) — an in-silico prediction, not a clinical call.

ADAM17 p.Ser770Pro

Q: How is Neonatal erythroderma-autoinflammation-inflammatory bowel disease syndrome inherited?

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

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.
