Is TRIM2 p.Ser51= (c.153T>C) pathogenic?

TRIM2 p.Ser51= (c.153T>C) is classified Likely benign in TRIM2 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-06-24). Very rare (popmax 0.000508%, nfe); Associated with Charcot-Marie-Tooth disease type 2R.

What condition is associated with TRIM2 p.Ser51= (c.153T>C)?

TRIM2 p.Ser51= (c.153T>C) is associated with Charcot-Marie-Tooth disease type 2R (ClinVar).

How common is TRIM2 p.Ser51= (c.153T>C) in the general population?

TRIM2 p.Ser51= (c.153T>C) is very rare (popmax 0.000508%, nfe) (gnomAD).

How is Charcot-Marie-Tooth disease type 2R inherited?

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

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
