Abstract

Friction Ridge Dysplasia is a rare genetic disorder in which the friction skin ridge units do not fuse together to form continuously flowing friction ridges. The skin affected by Friction Ridge Dysplasia is generally localized to one area and gives a similar appearance of the pebbled state of skin on the snout of a dog. Many authors have briefly discussed Friction Ridge Dysplasia in their publications; however, in-depth reflection as to the cause and rate of occurrence of Friction Ridge Dysplasia has not been documented. The objective of this study is to determine whether or not Friction Ridge Dysplasia is caused by certain factors such as, but not limited to, interfarnilial reproduction and genetic inheritance in Middle Eastern populations. The latent print examiners deployed to Afghanistan noticed a more frequent occurrence of Friction Ridge Dysplasia within record fingerprints R. Schenck (personal communication, April 25, 2013). Due to the typically infrequent occurrence of Friction Ridge Dysplasia in general casework, this type of data has never been collated and examined for the rate of occurrence in any population. The study sought to determine whether the preponderance of Friction Ridge Dysplasia is consistent between the Afghanistan and United States populations. The study indicated that Friction Ridge Dysplasia is dependent on country; however, the disease is independent of handedness.
