A phenotypic expansion has been proposed based on a cohort of six Brazilian probands that in addition to classic RTS also presented with poikiloderma and congenital cataracts. All shared the same deep intronic splice variant, c.588–2214 A>G, in trans with other LoF variants. The deep intronic variant has been shown to result in the inclusion of a cryptic exon in the mature RNA, resulting in a frame shift and premature termination codon. The authors speculate that the shared intronic variant, which they attribute to a founder effect, has residual normal splicing responsible for the phenotypic variation.
