Dermatoglyphics (fingerprint and palmprint).(Lakshmana et al., 2017).

Development of dermatoglyphics. (Bhat et al., 2014; Margi et al., 2016).

Characteristics of dermatoglyphics: genetic, unique, permanent. (Eboh, 2013; Bhat et al., 2014).

Uses of dermatoglyphics: identification, diagnosis, authentication, mirror of one’s potential and talent.

(Kucken and Newell, 2005; Offei et al., 2014; Atinga, 2017).

Genetic blood disorder that affects the haemoglobin within the RBC. (Wadood et al., 2012).

300,000 infants are born each year worldwide. (WHO, 2006).

Prevalent in West Africa (2-5)% and 2% in Ghana. (WHO, 2006; Asare et al., 2018).

18,000 babies born each year with SCA in Ghana. (Dennis-Antwi, 2018).

PRESENT STUDY

Solubility test and haemoglobin electrophoresis may give a false negative result when performed too early in infants.

(Wethers, 2000).

Infants less than 6 months possess predominantly foetal haemoglobin. (Piel, 2017).

Inaccuracy of diagnostic methods in babies less than 6 months.

(Pagrut and Chide, 2017).

Dermatoglyphics can be use to diagnose some genetic and non-genetic diseases.

(Andani et al., 2007). 3

PRESENT STUDY

Limited data correlating dermatoglyphics and SCA.

Limited dermatoglyphics parameters studied.

Ulnar loop dominated in both sickle cell anaemic and control groups with the sickle cell anaemic group recording the highest, this was not statistically significant.

For the absolute finger ridge count, there was a significant difference between the left hand of the sickle cell anaemic and control groups with the sickle cell anaemic group recording the highest.

Significant difference recorded between sickle cell anaemic and control groups for A-B and C-D palmar inter-digital ridge counts with the control group recording the highest in both.

CONCLUSION

PIC 310 dominated in the sickle cell anaemic group whilst PIC 300 dominated in the control group, this was statistically significant.

• Recorded 5 unreported PIC’s ( PIC 400, PIC 410, PIC 430, PIC 500 and PIC 520) in Ghana.

Significant difference recorded between sickle cell anaemic group and control group for ATD and DAT angles.

• ATD angle recorded highest in the sickle cell anaemic group.

• DAT angle recorded highest in the control group.

This study has established that there is some significant relationship between

dermatoglyphics and sickle cell anaemia.

CONCLUSION

Further analysis focusing on the minutiae or details of fingerprint (e.g. ridge dot, ridge ending, bifurcation, trifurcation, bridge, spur, enclosure, ridge crossing etc.)should be considered.

Finger ridge density between the sickle cell anaemic and control groups be studied rather than finger ridge count.

Method for finger ridge count should be reviewed because it is considered not being a true reflection of the total number of ridges present in a particular print.
