Gene: FARS2

The rating of this gene has been updated following NHS Genomic Medicine Service approval.

Created: 14 Mar 2022, 1:19 p.m. | Last Modified: 14 Mar 2022, 1:19 p.m.

Panel Version: 1.95

Review of literature did not reveal any adult onset cases - infantile and childhood-onset only

The 'Q3_21_phenotype' tag has been added to highlight that this is a childhood onset condition. Leaving the rating as Green, but with a recommendation for review at the next GMS panel update. This gene is already Green on the 'Hereditary spastic paraplegia - childhood onset v.2.18' panel.
