Abstract Background Alteration in the location and number of palmar creases has been found in association with certain disorders. The extra transverse digital crease (ETDC) has been reported in sickle cell disease. This study was carried out to determine the importance of ETDC as a diagnostic tool for sickle cell disease amongst Nigerians. Methods Medical students and student nurses with available hemoglobin electrophoresis records were studied. Their palms were examined for the presence of ETDC. Results An ETDC was present in 80 of 178 (44.9%) cases with genotype AA, 26 of 68 (38.2%) cases with sickle cell trait (AS, 65; AC, 3), and 10 of 22 (45.4%) cases with sickle cell disease (SS). Conclusions The results from our study show that the ETDC is not a diagnostic sign of sickle cell disease in Nigerians.
