Of the following reader, which one leading to increased translation initiation by binding to the 5’UTR m6A modifications, so that the translation can be initiated even without the cam in 5’UTR.  

A research team is studying a patient with a rare developmental disorder. Genomic sequencing reveals a heterozygous point mutation in the zinc finger domain of CTCF, abolishing its ability to bind DNA at several target loci. The patient exhibits craniofacial abnormalities, intellectual disability, and growth retardation — a phenotype resembling CTCF haploinsufficiency syndrome.   Question Based on the mutation described, which downstream consequence is most directly responsible for the patient’s phenotype?

Which conclusion best explains how silencing is maintained at these loci despite the loss of H3K27me3?
