Age and mutation type adjusted predicted scores of mood and anxiety and estimated weight-for-age z-scores. The error bars denote 95% confidence intervals. The RSBQ mood score ranges from 0 to 16 (n = 137) and the anxiety score ranges from 0 to 8 (n = 137). Higher scores represent higher frequency of adverse behavioural events. CT, C-terminal deletion; ET, early truncating; LD, large deletion; Neg/Unk, mutation negative or unknown.
