Sequence Features

 5V -> M (found in a patient with spastic paraplegia; unknown pathological significance; dbSNP:rs587777227). VAR_077848 dbSNP
 206P -> L (in dbSNP:rs138776588). VAR_075360 dbSNP
 344Y -> C (in ILLD; when assayed in yeast, induces a slight growth retardation and reduction in methionine incorporation; may interfere with efficient substrate binding; dbSNP:rs766466297). VAR_075361 dbSNP
 370F -> L (in ILLD; dbSNP:rs140467171). VAR_070872 dbSNP
 393A -> T (in ILLD; may act as a disease modifier aggravating the phenotype; found in patients that carried additional mutations C-344 and/or L-567; when assayed in yeast, does not exhibit any phenotype; when assayed in yeast in association with L-567, increases L-567- induced growth retardation and reduction in methionine incorporation; dbSNP:rs141340466). VAR_075362 dbSNP
 523I -> T (in ILLD; dbSNP:rs201555303). VAR_070873 dbSNP
 567S -> L (in ILLD; when assayed in yeast, reduces methionine incorporation; when assayed in yeast in association with T- 393, induces growth retardation and strong reduction in methionine incorporation; may interfere with efficient substrate binding; dbSNP:rs143592405). VAR_075363 dbSNP
 605D -> V (in ILLD; when assayed in yeast, induces a slight growth retardation and reduction in methionine incorporation; may interfere with efficient substrate binding; dbSNP:rs756021768). VAR_075364 dbSNP
 618R -> C (in CMT2U; loss of function mutation; dbSNP:rs587777718). VAR_073377 dbSNP
 683A -> D (in dbSNP:rs1054403). VAR_020459 dbSNP
 702R -> W (found in a patient with spastic paraplegia; unknown pathological significance; dbSNP:rs587777228). VAR_077849 dbSNP
