## TL;DR

A heart transplant recipient showed early asymmetric heart growth unrelated to rejection, linked to a genetic variant in the donor.

## Contribution

Highlights the importance of donor genetic screening to identify inherited conditions affecting transplant outcomes.

## Key findings

- A genetic variant in the folliculin gene was found in the donor and linked to Birt-Hogg-Dubé Syndrome.
- The donor's father also showed similar heart hypertrophy and the same genetic variant.
- Genetic evaluation of donor tissues can reveal non-transplant-related changes and identify carriers of pathogenic variants.

## Abstract

Um caso de um homem de 54 anos que se submeteu a um transplante cardíaco com hipertrofia assimétrica precoce não relacionada à rejeição. A análise genética do doador revelou uma variante no gene da foliculina, associada à síndrome de Birt-Hogg-Dubé. O rastreamento da família do doador identificou uma hipertrofia similar e a mesma variante genética no pai do doador. Embora a avaliação genética dos tecidos dos doadores não seja realizada rotineiramente, ela pode ser crucial para compreender alterações não relacionadas ao procedimento do transplante e identificar carreadores de variantes patogênicas.

A case of a 54-year-old man who underwent a heart transplant with early asymmetric hypertrophy unrelated to rejection. Donor’s genetic analysis revealed a variant in folliculin gene, associated with Birt-Hogg-Dubé Syndrome. Screening of the donor’s family uncovered a similar hypertrophy and same genetic variant in the donor’s father. Although genetic evaluation of donors’ tissues is not routine, it can be crucial for understanding changes unrelated to the transplant procedure and identifying carriers of pathogenic variants.
