Mild Dermatoglyphic Deviations in Adolescents with Autism Spectrum Disorders and Average Intellectual Abilities as Compared to Typically Developing Boys

Table 1

Fingerprint pattern counts, number of discordant finger pairs, atd-angles, and fluctuating asymmetry of atd-angles for boys with ASD and typically developing boys.

Trait	Character	ASD boys; M (SD)	Control boys; M (SD)	value	ES (Cohen’s )
Fingerprint patterns (Anscombe transformation of counts)	Number of whorls; (LH + RH)	2.52; (1.43)	2.42; (1.42)	0.75	0.07
	Number of arches; (LH + RH)	1.53; (0.56)	1.74; (1.04)	0.23	−0.25
	Number of discordant finger pairs	2.24; (0.88)	1.80; (0.72)	0.01	0.55
Atd-angles; ()	( + )/2	1.61°; (0.033°)	1.62°; (0.048°)	0.21	−0.38
		0.03°; (0.05°)	0.02°; (0.02°)	0.33	0.30

ASD = Autism Spectrum Disorders; ES = effect size; LH = left hand; M = mean (SD = standard deviation); RH = right hand.
