PCDH15, variants, traits, and what the research shows

PCDH15 - what this gene does

The variants catalogued for PCDH15 are predominantly linked to hearing-related traits; two variants in the dataset also carry a rare disease trait label.

Key takeaways

• PCDH15 variants are most consistently associated with hearing traits across the genetic data on file.
• Two variants in this gene are additionally flagged for rare disease associations.
• All 20 highlighted variants share a magnitude score of 5.50, a uniform signal level in this dataset.
• 1,559 total variants are recorded for this gene, making it a broadly catalogued genetic locus.
• These are population-level statistical signals and carry no predictive power for any individual.

Notable variants

Among the 20 highest-priority variants on file, those linked to hearing include rs1033803342, rs111033260, rs12246234, rs114137983, and rs1307471318, all at a magnitude of 5.50. Two variants stand apart by trait category: rs1209357687 and rs1326692199 are associated with rare disease phenotypes at the same magnitude level, though no further trait detail is available from the current dataset.

Trait associations

Hearing is the dominant trait theme across this locus: 18 of the 20 listed variants carry a hearing label, including rs1040514625, rs1056396947, rs1057516342, rs1057516892, rs1057517048, rs1057517325, rs111033363, rs111033436, rs111033445, rs111033449, rs111033516, rs1168400018, and rs1252259548. The consistent appearance of hearing as a trait across this many distinct variants suggests this gene is repeatedly detected in auditory genetics research. The two rare disease variants - rs1209357687 and rs1326692199 - have no further trait detail available in the current dataset.

Evidence quality

All 20 highlighted variants carry a uniform magnitude of 5.50, but no SNP-level research summaries are currently available for this gene, meaning effect sizes (such as odds ratios - the ratio of the odds of a trait in one group versus another - or beta coefficients), sample sizes, and replication status are not yet on file. Trait labels and magnitude scores derive from the variant index alone, and the individual-variant evidence base should be treated as preliminary until detailed study metadata are added. With 1,559 total variants recorded, the breadth of cataloguing is notable, but breadth of cataloguing is not the same as depth of evidence for any single variant.

What this is NOT

These variants represent population-level statistical associations and carry no predictive power for any individual's hearing status or disease risk. This page does not offer medical advice, diagnosis, or recommendations of any kind.
