What condition is associated with RET p.Glu673= (c.2019G>A)?

RET p.Glu673= (c.2019G>A) is associated with multiple endocrine neoplasia type 2 (ClinVar).

How common is RET p.Glu673= (c.2019G>A) in the general population?

RET p.Glu673= (c.2019G>A) is very rare (popmax 8.47e-05%, nfe) (gnomAD).

How is Multiple endocrine neoplasia type 2 inherited?

Typically Autosomal dominant (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.
