Facial Features

Nose wing breadth

Nose wing breadth describes the width of the nostrils (alae). It is a heritable feature studied in facial morphology research.

GWAS work has identified variants near craniofacial development genes linked to nose wing breadth.

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

Age, ethnicity, and overall facial structure also influence how nose wing breadth appears.

Understanding the Data

SNP: A specific genetic marker relevant to this trait (e.g., rs2588978)
Genotype: Your genetic makeup at the given SNP location (e.g., CC)
Variant allele: The alternative DNA sequence at the SNP site

Variant allele frequency: Percentage of population carrying this variant
Variant found: Whether the variant was detected in your DNA file

Variant Detected

PAX1 GeneCards

This gene is a member of the paired box (PAX) family of transcription factors. Members of the PAX family typically contain a paired box domain and a paired-type homeodomain. These genes play critical roles during fetal development. This gene plays a role in pattern formation during embryogenesis and may be essential for development of the vertebral column. This gene is silenced by methylation in ovarian and cervical cancers and may be a tumor suppressor gene. Mutations in this gene are also associated with vertebral malformations.

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.
