Shotgun metagenomic profiling of the fecal microbiome in <i>Lamp2</i> knockout mice reveals limited genotype-associated differences under standard housing

Background: Lysosomal pathways influence host–microbe interactions, but the microbiome consequences of lysosomal dysfunction remain incompletely defined. LAMP2 is required for autophagosome–lysosome fusion, and pathogenic variants in LAMP2 cause Danon disease. Whether Lamp2 loss alters the gut micro
