The coding region has been updated to include an additional segment in the coding region. This region corresponds to a tandem repeat encoding a 13 aa segment, which is present 3 times in the reference genome sequence. These tandem repeats are described in PMID:1577776. It should be noted that the majority of available transcript data represent an allele lacking one or more of these repeats, whereas this update represents the number of repeats found in the reference genome sequence.
