Neonatal jaundice icterometer, a piece of transparent plastic painted in five transverse strips of graded yellow lines, is not recommended. This is hand held, portable and rechargeable but expensive. When pressure is applied to the photoprobe, a xenon tube generates a strobe light, and this light passes through the subcutaneous tissue. The reflected light returns through the second fiber optic bundle to the spectrophotometric module. The intensity of the yellow color in this light, after correcting for the hemoglobin, is measured and instantly displayed in arbitrary units. Any of the following features suggests pathological jaundice: The signs which help detect pathological jaundice
Eye color both are localized in Chromosome 15. The gene "OCA2" (), when in a variant form, causes the pink eye color and hypopigmentation common in human albinism. (The name of the gene is derived from the disorder it causes, oculocutaneous albinism type II.) Different SNPs within "OCA2" are strongly associated with blue and green eyes as well as variations in freckling, mole counts, hair and skin tone. The polymorphisms may be in an "OCA2" regulatory sequence, where they may influence the expression of the gene product, which in turn affects pigmentation. A specific mutation within the "HERC2" gene, a gene that
