Sequence structure (FSSG)
ISFG minimum range, bracketing and kit coverage from the Forensic Sequence Structure Guide, FSSG v6.1 (STRidER; distributed as FSSG_v6-1_beta.xlsx).

This locus has two copies in GRCh38, and the FSSG describes each one in its own row: DYS385 a, DYS385 b. The ranges, CE equivalents and names below belong to the copy named above each block. A typing result usually lists the two alleles of the locus together; their order does not say which physical copy each one comes from.

The FSSG gives this row's sequence by pointing to another row instead of writing it out. STRhub shows no STRNaming name here until that sequence is resolved and reviewed.

[TTTC]14 [cctt]6

chrY:18,680,604-18,680,700 (97 bp)

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

Kit range does not cover the whole ISFG minimum range of this locus (chrY:18,680,604-18,680,700), 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.

Reported on the reverse strand. The forward strand DYS385 a is reverse complemented to DYS385 b.

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

Kit range does not cover the whole ISFG minimum range of this locus (chrY:18,639,700-18,639,784), 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.
