Coverage Plot of RNA-seq data for ALAS 2 gene RNA-seq reads for ALAS 2 gene are shown in genomic context (chrX:55,051,744-55,074,222). An apparently novel exon dubbed 4a, between exons 4 and 5 is expressed significantly more in SCD compared with controls (p = 0.0003). This exon has been previously observed as human EST BX367133, in a clone derived from T cells. The inset shows the region bounded by exons 4 and 5 with the coverage range expanded and truncated to 20 for each track.
