Afro-textured hair chart below is the most commonly used chart to help determine hair types: Different ethnic groups have observable differences in the structure, density, and growth rate of hair. With regard to structure, all human hair has the same basic chemical composition in terms of keratin protein content. Franbourg "et al." have found that Black hair may differ in the distribution of lipids throughout the hair shaft. Classical afro-textured hair has been found to be not as densely concentrated on the scalp as other follical types. Specifically, the average density of afro-textured hair was found to be approximately 190 hairs per
Cleft lip and palate transmembrane protein 1 may belong to a new gene family. This family also contains the "Homo sapiens" cisplatin resistance related protein CRR9p which is associated with CDDP-induced apoptosis. Cleft lip and palate transmembrane protein 1 Cleft lip and palate transmembrane protein 1 is a protein that in humans is encoded by the "CLPTM1" gene. It belongs to a family of several eukaryotic cleft lip and palate transmembrane protein 1 sequences. Cleft lip with or without cleft palate is a common birth defect that is genetically complex. The nonsyndromic forms have been studied genetically using linkage and candidate-gene association studies with only partial success
