MPS kits covering this locus

PowerSeq 46GY
ForenSeq Signature Prep/Plus and MainstAY (Does not cover the whole ISFG minimum range.)
IDSeek mYSTR (Does not cover the whole ISFG minimum range.)

Kit range does not cover the whole ISFG minimum range of this locus (chrY:8,558,328-8,558,409), 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.
