MPS kits covering this locus

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

Kit range does not cover the whole ISFG minimum range of this locus (chrY:16,631,669-16,631,724), 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

PowerSeq 46GY range shown is exclusive of primer, inferred bases may be included in GeneMarker HTS v2.6.1 output. Originally characterized on the reverse strand.
