The MYBPC3 MutationFeline HCM in Maine Coons is caused by a single base-pair change (G→C) in the cardiac myosin binding protein C gene (MYBPC3) — the A31P mutation. The inheritance pattern is autosomal dominant with incomplete penetrance: not all cats with one copy of the...

Is maine coon hypertrophic cardiomyopathy (hcm):... normal behavior?

This behavior is generally normal and serves important biological and social functions. However, sudden changes in frequency, intensity, or context may indicate an underlying health issue.

El MYBPC3 Mutation

Feline HCM en Maine Coons es caused por un single base-pair change (G→C) en el cardiac myosin binding protein C gene (MYBPC3) — el A31P mutation. El inheritance pattern es autosomal dominant con incomplete penetrance: no todo cats con one copiar de el mutation develop clinical disease, but homozygous cats (two copies) develop severe HCM en un young age. El mutation es present en approximately 34% de Maine Coons worldwide, con homozygous frequency de approximately 5%.

Screening Protocol

Annual echocardiography (cardiac ultrasound) starting en age 1 — measure izquierdo ventricular wall thickness en diastole (normal <5.5mm)
NT-proBNP blood probar — cardiac biomarker elevated cuando heart muscle es debajo stretch stress; screening probar, no diagnostic
Genetic testing identifies mutation carriers but cannot predict disease severity — echocardiography remains el gold standard
Auscultation alone es inadequate: arriba a 40% de HCM-affected cats tener no audible murmur

Clinical Signs de HCM

Muchos affected cats son asymptomatic hasta sudden death o acute heart failure. Advertencia signs: increased respiratory rate en rest (>30 breaths/minute en home), abrir-mouth breathing, hind-limb paralysis de aortic thromboembolism (saddle thrombus — un blood clot lodges en el aortic bifurcation, cutting fuera blood flow a hind legs; esto es excruciatingly painful y tiene un poor prognosis), lethargy, y decreased appetite. Any Maine Coon exhibiting estos signs needs emergency veterinary evaluation dentro hours.
