This paper uses the terms ‘first degree consanguineous’, ‘first degree relatives’ and ‘first degree’ erroneously; these should read ‘first cousin marriages’ throughout the paper. It also uses ‘second degree’ erroneously, and this should read ‘second cousin marriages’ throughout the paper.

In Tables 5 and 6 the terms ‘Not relatives’, ‘First degree relatives’ and ‘Other relatives’ should read ‘Not related’, ‘First cousin marriages’ and ‘Other consanguineous marriages’, respectively.

These corrections are being made because the terms used in the manuscript should have been in line with common usage.
