โฆ Synopsis
Salla disease is an inherited lysosomal storage disorder caused by accumulation of free sialic acid in the lysosomes. Lamp genes, lamp A and lamp B (lysosome associated membrane proteins), are the first known genes encoding for human lysosomal membrane proteins. Absence of linkage in a large group of families shows that lamp genes are not involved in Salla disease. The lamp genes were localized, using Southern hybridization in hamster--human hybrid cell panels, to chromosomes 13 (lamp A) and X (lamp B).

The gene that encodes the human โฃ2 subunit of the inhibitory glycine receptor (GLRA2) is located on the X chromosome (Xp22.2) in a candidate region for a number of neurological disorders. Recently, an exclusion mapping strategy identified this region to be concordant in familial Rett syndrome (RTT)
