abstract = {The TAS2R38 gene carries markers for phenylthiocarbamide
(PTC) sensitivity. Various studies have investigated the
genotype-phenotype association pattern for bitter tasting
ability and other factors in different populations. However,
a paucity of such information for endogamous Indian
populations is the reason behind this study.To study the
association of phenylthiocarbamide (PTC) sensitivity with
TAS2R38 gene variations in Koṅkaṇī Sārasvata Brahmin
population.We studied the association of the alleles
rs714598, rs1726866, rs10246939 with PTC sensitivity and
other factors in the Koṅkaṇī Sārasvata Brahmin
population. DNA was extracted from 114 individuals belonging
to the Koṅkaṇī Sārasvata Brahmin community. The
TAS2R38 gene was sequenced to find the genotype distribution
pattern. The association between genotype and phenotype was
checked using the Chi-Square test and multifactorial
logistical regression.We observed a $58.8\%$ frequency of
the AVI haplotype, which is the most prevalent in European
populations. A higher number of non-taster haplotypes and
diplotypes were observed in Koṅkaṇī Sārasvata
Brahmins, with the allele rs10246939 showing a significant
association with PTC bitter taste sensitivity in both
allelic (p = 8.6 × 10-4; Allele-G, OR = 3.57 $[95\%$ CI =
1.66-7.69]) and genotype-based (p = 6.9 × 10-4;
genotype-AG, OR = 3.11 $[95\%$ CI = 0.73-13.20];
genotype-GG, OR = 40 $[95\%$ CI = 3.58-447.03]) tests.Our
results are in line with earlier studies, which report an
association between PTC sensitivity and the TAS2R38 gene in
different populations. In the global context, Koṅkaṇī
Sārasvata Brahmins, who are mostly distributed along the
southwestern coast of India, show a PTC sensitivity pattern
slightly similar to that of West Eurasian populations. Our
findings suggest ancestry specific selection in TAS2R38 gene
variations for taste sensitivity at global level.},
