BACKGROUND/PURPOSE: In mice, biotin deficiency is one of the most potent

clefting factors. Increased 3-hydroxyisovalerylcarnitine (C5OH) is regarded as a

biomarker of biotin deficiency. This retrospective study was undertaken to

determine whether increased C5OH in newborns is associated with orofacial clefts.

MATERIALS AND METHODS: Seventy newborns with non-syndromic cleft lip with or

without cleft palate and 140 control newborns without congenital anomalies were

investigated. Whole-blood C5OH concentrations were measured using tandem mass

spectrometry.

RESULTS: The median (interquartile range, IQR) concentrations of C5OH in

patients with clefts and controls were 0.16 (0.13-0.22)μmoll(-1) and 0.17

(0.13-0.20) μmoll(-1), respectively (p=0.90). The receiver operating

characteristic analysis did not find out cut-off values for C5OH discriminating

between cases and controls.

CONCLUSION: There appears to be no association between biotin deficiency, as

indexed by an increase of C5OH, and orofacial clefts in the investigated group of patients.
