Is TTN p.Pro17567= (c.52701A>G) pathogenic?

TTN p.Pro17567= (c.52701A>G) is classified Likely benign in TTN (ClinVar, Single submitter, 1 submitter; last evaluated 2024-05-01). Absent from gnomAD v4.1; Associated with dilated cardiomyopathy 1G.

What condition is associated with TTN p.Pro17567= (c.52701A>G)?

TTN p.Pro17567= (c.52701A>G) is associated with dilated cardiomyopathy 1G, autosomal recessive limb-girdle muscular dystrophy type 2J (ClinVar).

How common is TTN p.Pro17567= (c.52701A>G) in the general population?

TTN p.Pro17567= (c.52701A>G) is absent from gnomAD v4.1 (gnomAD).

How is Familial isolated dilated cardiomyopathy inherited?

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