Abstract

Native American genetic variation remains underrepresented in most catalogs of human genome sequencing data. Previous genotyping efforts have revealed that Mexico's Indigenous population is highly differentiated and substructured, thus potentially harboring higher proportions of private genetic variants of functional and biomedical relevance. Here we have targeted the coding fraction of the genome and characterized its full site frequency spectrum by sequencing 76 exomes from five Indigenous populations across Mexico. Using diffusion approximations, we modeled the demographic history of Indigenous populations from Mexico with northern and southern ethnic groups splitting 7.2 KYA and subsequently diverging locally 6.5 and 5.7 KYA, respectively. Selection scans for positive selection revealed BCL2L13 and KBTBD8 genes as potential candidates for adaptive evolution in Rarámuris and Triquis, respectively. BCL2L13 is highly expressed in skeletal muscle and could be related to physical endurance, a well-known phenotype of the northern Mexico Rarámuri. The KBTBD8 gene has been associated with idiopathic short stature and we found it to be highly differentiated in Triqui, a southern Indigenous group from Oaxaca whose height is extremely low compared to other Native populations.

  • PBS identified alleles in multiple genes that have already been identified as targets of adaptive introgression, as well as in novel candidate genes, including some that govern development and cardiac function.

    “We used PBS to identify possible candidates for adaptive introgression that were unique to admixed American populations and identified alleles in multiple genes that have already been identified as targets of adaptive introgression (Racimo et al. 2017, 2018; Ávila-Arcos et al. 2020), as well as in novel candidate genes, including some that govern development and cardiac function.”

    The Results (Adaptive Evolution in Native Mexicans) report a PBS signal in FAP and describe it as previously suggested to be under adaptive archaic introgression; they also list candidate genes involved in differentiation and cardiac muscle contraction. The Discussion (Targets of Adaptive Evolution in NM) confirms an archaic haplotype in Native Mexicans. This source supports FAP as one example, but does not establish that multiple genes it identified were already targets of adaptive introgression. (LLM, conf=0.83)

  • Some of the regions with high-frequency archaic alleles contain genes already identified as adaptively introgressed in Indigenous American populations, including IFIH1/FAP and WARS2 in PEL, and LRRK2/MUC19 in MXL.

    “Some of these regions contain genes that have already been identified as adaptively introgressed in Indigenous American populations, including IFIH1/FAP (Ávila-Arcos et al. 2020) and WARS2 (Racimo et al. 2018), identified in PEL, and LRRK2/MUC19 (Reynolds et al. 2019), identified in MXL.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
