Leidy Yamileth Gavarrete, a native and citizen of El Salvador, petitions this court to review the decision of the Board of Immigration Appeals (BIA) dismissing her appeal from the immigration judge’s denial of her application for asylum, withholding of removal, and for relief under the Convention Against Torture (CAT). Gavar-rete argues, for the first time in this court, that her claim for asylum and withholding of removal is based on her membership in a particular social group: “young females of Central America.” Because Gavarrete did not raise this argument before the BIA, the issue is unexhausted, and this court lacks jurisdiction to consider it. See Omari v. Holder, 562 F.3d 314, 317-19 (5th Cir.2009); Wang v. Ashcroft, 260 F.3d 448, 452-53 (5th Cir.2001); 8 U.S.C. § 1252(d)(1).
Gavarrete does not directly challenge in her petition for review or brief the BIA’s *51determination that she failed to establish past persecution or a well-founded fear of persecution on account of a statutorily protected ground. Rather, she concedes that she did not argue before the BIA or IJ that she was a member of the particular social group consisting of “young females of Central America.” She also does not challenge the BIA’s determination that she had waived any claim for relief under the CAT. Gavarrete has abandoned these issues by failing to brief them. Soadjede v. Ashcroft, 324 F.3d 830, 833 (5th Cir.2003).
Accordingly, Gavarrete’s petition for review is DENIED in part and DISMISSED in part for lack of jurisdiction.
