BRCA1, which regulates cell cycle progression, DNA damage signalling and repair, and maintenance of genomic integrity, interacts with NRF2 either directly, through its ETGE motif, preventing KEAP1-dependent ubiquitination of NRF2 and protecting cells against OS, or indirectly, through the interaction with CBP or with c-Myc [186]

While it is perhaps somewhat surprising that no group differences in metabolite concentrations were found, either for GABA (as has been shown before) or for GSH, we note that autism is an extremely heterogeneous condition, and that group differences, if present, may be small and relatively uninformative in understanding the broader autism phenotype(Loth et al., 2021)
Think of it like this: HGH is a Swiss Army knife - lots of tools, lots of effects, some wanted, some not
