Sequence Features
| 342 | R -> S (in pRTA-OA; decreased localization to the basolateral membrane; mistargeting to the apical membrane probably explains the loss of the cotransporter activity; dbSNP:rs121908856) VAR_024751 dbSNP | ||
| 471 | S -> L (in pRTA-OA; mistargeting to the apical membrane and altered function) VAR_024752 | ||
| 529 | T -> S (in pRTA-OA; decreased cotransporter activity) VAR_024753 | ||
| 530 | G -> R (in pRTA-OA; decreased cotransporter activity; no effect on localization to the basolateral membrane) VAR_071661 | ||
