Finger length ratio

Physical Traits

The 2D:4D ratio compares the length of the index finger (2D) to the ring finger (4D). It is studied as a research marker of prenatal androgen exposure.

GWAS work has identified variants linked to digit length differences, with some overlap with sex hormone signaling.

This result reflects research-level variation in finger length ratio and is not a measure of personality, performance, or health.

Hand and measurement method, age, and population can affect any actual ratio.

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.

SMOC1

This gene encodes a multi-domain secreted protein that may have a critical role in ocular and limb development. Mutations in this gene are associated with microphthalmia and limb anomalies. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2011]

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.
