## Abstract

The invention provides methods of treating α-galactosidase A deficiency. Dosage forms, methods of administration, and methods of analyzing human α-galactosidase A are also included.

## Claims

### Claim 1

A kit for the treatment of α-Gal A deficiency, comprising: (a) a human α-Gal A glycoprotein preparation; and (b) instructions to administer the preparation to a subject in need thereof, wherein the serum clearance of the α-Gal A preparation from subject's circulation is less than 4 mL/min/kg on the linear portion of the AUC vs. dose curve, wherein the α-Gal A glycoprotein preparation has the following four characteristics:
(1) has less than 35% tri- and tetra-sialylated glycans combined;
(2) has greater than 50% complex glycans;
(3) has less than 45% phosphorylated glycans; and
(4) has a ratio of sialylated glycans to phosphorylated glycans greater than 1.

### Claim 2 (depends on 1)

The kit of claim 1, wherein the serum clearance of the α-Gal A preparation from subject's circulation is 3.5 mL/min/kg or less on the linear portion of the AUC vs. dose curve.

### Claim 3 (depends on 1)

The kit of claim 1, wherein the serum clearance of the α-Gal A preparation from subject's circulation is 3.0 mL/min/kg or less on the linear portion of the AUC vs. dose curve.
