Vacuolating cytotoxin (vacA) alleles of Helicobacter pylori comprise two geographically widespread types, m1 and m2, and have evolved through limited recombination [PDF]
, 1999 Vacuolating cytotoxin (vacA) alleles of Helicobacter pylori vary, particularly in their mid region (which may be type m1 or m2) and their signal peptide coding region (type s1 or s2).

Sex-specific recombination rates and allele frequencies affect the invasion of sexually antagonistic variation on autosomes [PDF]
Journal of Evolutionary Biology 26 (2013) 2428, 2013 The introduction and persistence of novel sexually antagonistic alleles can depend upon factors that differ between males and females. Understanding the conditions for invasion in a two-locus model can elucidate these processes. For instance, selection can act differently upon the sexes, or sex-linkage can facilitate the invasion of genetic variation ...

Phenotypic continuum of NFU1‐related disorders
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2025-2035, December 2022., 2022 Abstract Bi‐allelic variants in Iron–Sulfur Cluster Scaffold (NFU1) have previously been associated with multiple mitochondrial dysfunctions syndrome 1 (MMDS1) characterized by early‐onset rapidly fatal leukoencephalopathy. We report 19 affected individuals from 10 independent families with ultra‐rare bi‐allelic NFU1 missense variants associated with a
