The rating of this STR has been updated to Green following NHS Genomic Medicine Service approval.Created: 1 Feb 2023, 12:39 p.m. | Last Modified: 1 Feb 2023, 3:14 p.m.
Panel Version: 2.6
Comment on list classification: There is sufficient evidence to promote this STR to Green at the next GMS panel update.
The AR gene was Green on this panel for Kennedy disease, MIM# 313200 (https://panelapp.genomicsengland.co.uk/panels/79/gene/AR/) however, this has been flagged to be downgraded as the disease mechanism is an expansion of 36 or more CAG trinucleotide repeats in the AR gene and there is a lack of phenotypic relevance for SNVs. STR testing is appropriate route for detecting cases.Created: 1 Jul 2021, 1:37 p.m. | Last Modified: 11 Nov 2021, 3:20 p.m.
