Yet, the effect failed to reach significance for both homozygous allele combinations (long/long, consistent: 357; inconsistent: 328; χ2 = 1.23; p = 0.27 and short/short, consistent: 30; inconsistent: 25; χ2 = 0.46; p = 0.5).
Discussion Our data show a statistical trend supporting earlier findings for an association of PCSK6 with handedness.
Replication in independent cohorts of individuals with RD revealed the same effect for the minor rs11855415 allele, while the same allele showed a significant trend towards reduced hand skill in the general population [17] .
