Arina Puzriakova (Genomics England Curator)

Comment on list classification: FMR1 should be demoted from Green to Red at the next GMS panel update as the disease mechanism for FXTAS (includes ataxia) is repeat expansions and SNVs are not relevant. Furthermore, the FMR1_CGG STR entity will not be added as FXTAS is a late-onset condition and this panel feeds into the childhood-onset ataxia super panel (R55). The STR is already Green on the R45 Hereditary ataxia - adult onset (v2.13) panel.

Dmitrijs Rots (Children's Clinical University Hospital)

Red List (low evidence)

Only CGG expansion causes movement disorder. Should be excluded from the panel, as would result in SNV analysis.
