One of the most notable genes in PAR1 is the pseudoautosomal boundary gene, which plays a role in the initial recognition and pairing of the X and Y chromosomes. Other genes encode for proteins that are part of the ribosomal machinery or are involved in basic metabolic pathways, highlighting that these regions are not evolutionary relics but active contributors to genomic integrity.

These conditions underscore the vital role these seemingly interchangeable regions play in normal development. There are two primary identified regions in humans: PAR1, located at the very tips of the short arms (p-arms), and PAR2, found on the long arms (q-arms), although PAR2 is significantly smaller and less active.
A deletion or duplication in a pseudoautosomal region can lead to a variety of clinical features, including skeletal abnormalities, intellectual disability, and gonadal dysgenesis. In contrast, because genes in the pseudoautosomal region recombine, they can be passed down by either parent to either sex.

The Definition and Location of Pseudoautosomal Regions The term pseudoautosomal refers to the small regions of homology between the X and Y chromosomes where these two sex chromosomes pair and recombine during male meiosis. Key Genes and Their Functions Several important genes reside within the pseudoautosomal regions, many of which are directly involved in the fundamental processes of cellular function and development.
