Resumen
HOYOS, DIEGO HERNÁN et al. Familial hypercholesterolemia: a case of a family located in Armenia - Quindío (Colombia). Salud, Barranquilla [online]. 2022, vol.38, n.1, pp.352-366. Epub 04-Mayo-2023. ISSN 0120-5552. https://doi.org/10.14482/sun.38.1.616.399.
Introduction:
Familial hypercholesterolemia (FH) is a rare autosomal dominant genetic disease caused by a chromosome 19 mutation. It is the main cause of premature cardiovascular disease. Pathogenic mutations which cause FH are related to the LDL receptor (LDLr), B-100 apolipoprotein (Apo-B100) and type 9 subtilisin/kexin convertase protein (PCSK9), causing blood cholesterol increase and impairment of the LDLr pathway in up to 80% of patients diagnosed with FH.
We present the case of 4 patients belonging to the same family and who present pathogenic mutations leading to diverse kinds of cardiovascular and systemic disease.
Discussion:
The case report we are presenting is based on the suspicion of FH according to the dutch criteria. These patients had the LDLr gene mutation related to FH. However, this mutation has not been thoroughly studied. The ac 11G>T variant was reported for the first time in Poland by Chmara. In Colombia, Lopez found 3 mutations identified as variant a c.11G > A, variant n c.416A > G and variant c.1187G > A.
Conclusion:
FH is rare in Colombia. Early diagnosis and healthcare worker awareness must be highlighted to improve the quality of life and decrease the cardiovascular risk of patients.
