“…The activity of the COMT enzyme is influenced mainly by a functional single nucleotide polymorphism (rs4680; G to A) in the COMT coding region that causes a Val158Met aminoacid substitution in the corresponding protein, with the Val allele exhibiting a 3- to 4-fold increase in enzyme activity compared to the Met allele [ 29 , 30 ]. Considering that the COMT Val158Met gene is associated with several traits related to NSSI behaviours, including emotion regulation [ 31 , 32 ], borderline personality disorders [ 33 , 34 ] and suicidal behaviours [ 35 , 36 ], we hypothesize that the COMT Val158Met gene might directly moderate the relationship between harsh parenting and NSSI.…”

“…Therefore, it is reasonable to assume that personality traits which are likely to be partially regulated by the MB-COMT gene, such as impulsivity (BAS) (Smederevac et al, 2022) and reactive aggression (Fight) as a response to a perceived threat (Reuter et al, 2006), will also be associated with differences in the level of MB-COMT DNAm. Moreover, previous studies have shown evidence that associate MB-COMT DNAm with personality disorders (Dammann et al, 2011;Thomas et al, 2019).…”

“…Um aumento da metilação do promotor PRIMA1 em amostras de sangue periférico e uma diminuição dos níveis de metilação do promotor distal 5´região ETS do rDNA em pacientes TPB foi relatado por Tescher, Gotthardt, Dammann & Dammann (2016). Os genes KCNQ1proteína do canal de potássio controlado por voltagem -MCF2, NINJ2 (proteína induzida por lesão nervosa, NINJURIN2), COMTenvolvido na degradação de catecolaminasapresentaram, respectivamente, aumento da metilação em 1,5, 1,1, 1,2 e 1,07 vezes (Tescher et al, 2013;Thomas et al, 2019).…”

“…COMT apresenta duas isoformas, uma ligada a membrana dos tecidos do sistema nervoso central, MB-COMTessa forma no cérebro de pacientes TPB é significativamente hipometiladae outra solúvel nos tecidos periféricos, S-COMT. As análises acerca da metilação são realizadas a partir de fluídos e sangue periférico, portanto, apenas o S-COMT é plausível de análise in vivo, apresentando metilação aumentada nos sítios CpG 1 e CpG 2 (Dammann et al, 2011;Thomas et al, 2019).…”
