Middle phalangeal hair distribution in a Sardinian population sample.

Data relating to middle phalangeal hair (MPH) among unrelated individuals of both sexes born and living in Sardinia are presented. The occurrence of MPH is generally manifested on the 3-4-5 digits of both hands in the two sexes. The observed sex differences are statistically non-significant. The Sardinian sample seems to have a marked decrease in the frequency of individuals with MPH with regard to Mediterranean and other European populations.
