PER CURIAM:
Alice M. Deane appeals the district court's order granting the Commissioner of Social Security's summary judgment motion in her action seeking review of the Commissioner's decision denying her disability insurance and supplemental security income benefits under the Social Security Act. On appeal, we confine our review to the issues raised in the Appellant's brief. See 4th Cir. R. 34(b). Because Deane's informal brief does not challenge the basis for the district court's disposition, Deane has forfeited appellate review of the court's order. Accordingly, we affirm the district court's judgment. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
To the extent Deane seeks to submit evidence she did not present in the administrative proceeding, we decline to consider it. See Smith v. Chater, 99 F.3d 635, 638 n. 5 (4th Cir. 1996).
AFFIRMED.
