Is ATM p.Phe357Ser (c.1070T>C) pathogenic?

ATM p.Phe357Ser (c.1070T>C) is classified Uncertain significance in ATM (ClinVar, Single submitter, 1 submitter; last evaluated 2021-02-13). AlphaMissense: likely pathogenic (0.8362); Absent from gnomAD v4.1; Associated with ataxia telangiectasia.

What condition is associated with ATM p.Phe357Ser (c.1070T>C)?

ATM p.Phe357Ser (c.1070T>C) is associated with ataxia telangiectasia (ClinVar).

How common is ATM p.Phe357Ser (c.1070T>C) in the general population?

ATM p.Phe357Ser (c.1070T>C) is absent from gnomAD v4.1 (gnomAD).

How is Ataxia-telangiectasia inherited?

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

What do computational predictors say about ATM p.Phe357Ser (c.1070T>C)?

AlphaMissense predicts likely pathogenic (score 0.8362) — an in-silico prediction, not a clinical call.

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

AlphaMissense carries the ACMG weight for missense; REVEL is an independent agreement signal.
