However, smallholder farmers in Rwanda have benefited from other livestock initiatives and development programmes. Capturing and documenting the genetic diversity, is critical in part as a key contribution to genomic resource required to support dairy development in Rwanda. A total of 2,229 crossbred animals located in all dairy-producing regions of Rwanda were sampled. For each animal, a hair sample was collected and genotyped by using the Geneseek Genomic Profiler (GGP, Neogen Geneseek^®) Bovine 50 K (n = 1,917) and GGP Bovine 100 K arrays (n = 312). The combined dataset was subject to quality control, data curation for use in population genetics and genomic analyses. To assess the genetic structure and diversity of the current population, key analyses for population structure were applied: Principal Component Analysis (PCA), population structure and diversity, admixture analysis, measures of heterozygosity, runs of homozygosity (ROH) and minor allelic frequency (MAF). A dataset of global dairy population of European taurine, African indicus and African taurus (n = 250) was used as reference. Results showed that Rwanda cattle population is highly admixed of diverse pure and crossbred animals with average MAF of 33% (standard error; se = 0.001) with proportion of foreign high yielding (taurine) dairy breeds of Jersey Island (18%); 12% non-Island Jersey and 42% Holstein-Friesian ancestries. Two African Bos taurus and five Bos indicus breeds contributed 28% of their genetics. Genetic distances were highest in Gir and N'dama (0.29); and Nelore and N'dama (0.29).

These mutations disrupt cystine efflux, leading to its accumulation in lysosomes and subsequent cellular damage. While more than 140 mutations have been identified, the functional and structural impacts of many nonsynonymous single nucleotide polymorphisms (nsSNPs) remain poorly understood. Nonsynonymous SNPs are of particular interest because they can directly alter protein structure and function, potentially leading to disease. Clinically, cystinosis most often presents with renal Fanconi syndrome, photophobia and vision loss due to corneal cystine crystals, and progressive neuromuscular complications such as distal myopathy and swallowing difficulties This study aimed to identify deleterious nsSNPs in the CTNS gene and evaluate their effects on cystinosin stability, structure, and function via computational tools and molecular dynamics simulations.</p><p><strong>Results: </strong>From a dataset of 12,028 SNPs, 327 nsSNPs were identified, among which 19 were consistently classified as deleterious across multiple predictive tools, including SIFT, PolyPhen, and molecular dynamics simulations.

Molecular dynamics simulations revealed that these mutations significantly increase local flexibility, alter hydrogen bonding patterns, and enhance solvent accessibility, resulting in structural perturbations. Notably, D305G and F142S disrupted the transmembrane domains essential for the function of cystinosin, whereas compared with the wild-type protein, G309V resulted in increased stability.
