Distance between eyeballs

Facial Features

Distance between eyeballs is a heritable facial measurement studied in research on facial morphology.

GWAS work has identified variants near genes involved in craniofacial development that influence eye spacing.

This result reflects research-level variation in facial biology and is not a measurement of any individual's face.

Age, facial growth in childhood, and surrounding facial features can also affect how eye spacing appears.

Genes analyzed

Gene summaries include genomic locations and associated markers. A detected genotype does not by itself indicate a health condition.

Understanding the data

SNP: A specific genetic marker relevant to this trait.
Genotype: The DNA letters reported at a marker location.
Variant allele: The alternative DNA sequence at the SNP site.
Variant allele frequency: The reported percentage of the reference population carrying this variant.
Variant found: Whether the variant was detected in your DNA file.

1 of 1 genes have detected genotypes.

COL17A1

This gene encodes the alpha chain of type XVII collagen. Unlike most collagens, collagen XVII is a transmembrane protein. Collagen XVII is a structural component of hemidesmosomes, multiprotein complexes at the dermal-epidermal basement membrane zone that mediate adhesion of keratinocytes to the underlying membrane. Mutations in this gene are associated with both generalized atrophic benign and junctional epidermolysis bullosa. Two homotrimeric forms of type XVII collagen exist. The full length form is the transmembrane protein. A soluble form, referred to as either ectodomain or LAD-1, is generated by proteolytic processing of the full length form.

DNA Genics reports genotypes based on the 'positive' strand of the human genome reference sequence (build 37/HG19). Other companies may use the opposite strand, so genotypes may need conversion for comparison.
