The clinical markers for a variety of neurodevelopmental diseases and chromosomal abnormalities include dermatoglyphic features. In the first and second trimesters of pregnancy, the ectodermic layer is where dermatoglyphic patterns and neural tissues begin to take shape; at this point, the environment has little impact on them. Autism is a complicated neurodevelopmental condition marked by severe behavioral, social, and communication functioning problems. In the Bengalee population of West Bengal, India, the present study aimed to comprehend the connection between Abnormal Palmar Flexion Creases (APFCs) and autism. The standard ink and roller method was used to collect the bilateral palm prints of 100 participants-67 males and 33 females-diagnosed as autistic and 100 participants-55 males and 45 females-who were healthy controls-for this purpose from the Bengalee linguistic groups of West Bengal. The findings showed that the left and right hands of autistic males and females had significantly (p<0.05) more APFCs, single transverse creases, and Sydney line than did control males and females. The current study revealed that compared to controls without sex or side differentiations, autistic patients have more Sydney lines and single transverse creases. The results of the current investigation proposed that new early diagnostic criteria for autism may include the obvious existence of APFCs.
