Is ATM p.Asp211= (c.633C>T) pathogenic?

ATM p.Asp211= (c.633C>T) is classified Likely benign in ATM (ClinVar, Multiple submitters, 2 submitters; last evaluated 2022-10-31). Absent from gnomAD v4.1; Associated with ataxia telangiectasia.

What condition is associated with ATM p.Asp211= (c.633C>T)?

ATM p.Asp211= (c.633C>T) is associated with ataxia telangiectasia, hereditary neoplastic syndrome (ClinVar).

How common is ATM p.Asp211= (c.633C>T) in the general population?

ATM p.Asp211= (c.633C>T) 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.
