Abstract
This study examined whether dermatoglyphic characteristics are associated with the α-actinin isoform 3 (ACTN3) R577X sequence variant, employing descriptive and comparative approaches. Boys (N=82) were classified according to the dermatoglyphic configuration of their digital impressions into the following groups: Anaerobic Power (AP=8); Speed Resistance (SR=44); Pure Force (PF=5), and Aerobic Resistance (AR=25). All of the AP group subjects (9.76% of the subjects) had a genetic predisposition for anaerobic power performance, with 37.5% being RR homozygotes and 62.5% being RX heterozygotes. The dermatoglyphic profiles, correlated with the ALW fingerprint formulas, classified the SR group (53.66% of the subjects) as having speed resistance. The PF group (6.09% of the subjects) notably all had AL fingerprints and an absence of W. Finally, the AR group (30.49% of the subjects) had a predisposition for aerobic capacity. In conclusion, dermatoglyphic features can be associated with the R577X allelic variant of the ACTN3 gene, as much through anaerobic muscle power profiling as through the ACTN3 genotype.
Key words: alpha-actinin; fingerprint; genetic polymorphism.

Sažetak
Cilj ovoga istraživanja bio je istražiti postoji li odnos između dermatoglifskih karakteristika i α-aktinin izomorf 3 (ACTN3) R577X varijante. U istraživanju su korišteni deskriptivni i komparativni pristup. Dječaci (N = 82) su klasificirani u skupine na temelju dermatoglifske konfiguracije njihovih digitalnih otisaka na sljedeći način: anaerobna snaga (AP = 8), otpornost pri brzini (SR = 44), čista snaga (PF = 5) i aerobna otpornost (AR = 25). Svi sudionici iz skupine AP (9,76% sudionika) imali su gensku predispoziciju za izvedbu za koju je potrebna anaerobna snaga. Od toga je 37 (5%) bilo homozigotna i 62.5% heterozigotna genotipa. Dermatoglifski profili u korelaciji s formulama otiska prstiju iznjedrili su klasifikaciju SR skupine (53.66% sudionika) kao skupinu s otpornošću pri brzini. Svi sudionici PF skupine (6.09% svih sudionika) imali su Al otiske prstiju i odsutnost W. Na kraju, AR skupina (30.49% svih sudionika) je imala predispoziciju za aerobni kapacitet. Zaključak je da dermatoglifske karakteristike mogu biti povezane s R577X aleličkom varijantom ACTN3 gena, profiliranjem anaerobne mišićne mase, kao i ACTN3 genotipa.
Ključne riječi: α-aktinin; otisak prsta; genski polimorfizam
