MPS kits covering this locus

ForenSeq Signature Prep (Does not cover the whole ISFG minimum range.)

Kit range does not cover the whole ISFG minimum range of this locus (chrX:134,284,955-134,285,044), according to the kit ranges in the FSSG. Bases of the minimum range outside a kit's range are not sequenced by that kit; bases filled in from the reference should be identified as such.

Notes from the FSSG
