Protocadherin 11 X-linked, also known as PCDH11X, is a protein which in humans is encoded by the PCDH11X gene.[1][2]

Function

This gene belongs to the protocadherin gene family, a subfamily of the cadherin superfamily. The encoded protein consists of an extracellular domain containing 7 cadherin repeats, a transmembrane domain and a cytoplasmic tail that differs from those of the classical cadherins. The gene is located in a major X/Y block of homology and its Y homolog (PCDHY), despite divergence leading to coding region changes, is the most closely related cadherin family member. The protein is thought to play a fundamental role in cell–cell recognition essential for the segmental development and function of the central nervous system. Transcripts arising from alternative splicing encode isoforms with variable cytoplasmic domains.[1]

Clinical significance

In a genome-wide association study, the PCDH11X gene has been linked as a risk factor in late onset Alzheimer's disease,[3] but other studies on different populations [4][5][6][7] could not confirm the initial association. The clinical significance of this gene is unclear, and the gene might play different roles in different population specific contexts.
