SLC6A5 A89E - GET-Evidence

Note: This variant has not been sufficiently evaluated by a GET-Evidence editor.

To be considered sufficiently evaluated a variant must have both "variant evidence" and "clinical importance" scores filled in.

Please help improve GET-Evidence by evaluating evidence for this variant!



(SLC6A5 Ala89Glu)

Short summary

Reported causative for hyperekplexia in 2006, but later reports find an allelic frequency of 0.02 in controls and in vitro expression indistinguishable from wildtype.
