What condition is associated with TRIM2 p.Thr358= (c.1074G>A)?

TRIM2 p.Thr358= (c.1074G>A) is associated with Charcot-Marie-Tooth disease type 2R (ClinVar).

How common is TRIM2 p.Thr358= (c.1074G>A) in the general population?

TRIM2 p.Thr358= (c.1074G>A) is very rare (popmax 0.00329%, sas) (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.
