.06). F, fibrosis was highest for R403Q(three) when compared with HCMsmn (P 0.05). G, RNA was extracted three instances from a tissue sample of every patient. The relative expression of your R403Q and wildtype alleles was quantified at the very least in duplicate. Analysis of mutant R403Q mRNA revealed a deviation from the 50:50 ratio (allelic imbalance) in R403Q(1) having a fraction of mutated mRNA getting drastically reduce than in R403Q(two) (# P 0.0001) and R403Q(three) (+ P 0.0002), both displaying no allelic imbalance.
