Variant evidence. Especially the classifications that disagree.
Uncertain significance remains the defensible classification from the supplied record. The cited meiotic context concerns β-tubulin isotypes in C. elegans, not an identified human LRRCC1 allele. Without the exact variant, human segregation, and matched allele-specific functional evidence, it cannot resolve the classification conflict.
Uncertain significance remains better supported than likely pathogenic for the LRRCC1 variant. The C. elegans β-tubulin-isotype study adds acentrosomal oocyte-meiosis context, but its title provides no evidence about LRRCC1 or a human allele. A mechanistic analogy cannot substitute for the exact variant, matched controls, allele-specific effect, and human segregation data.
Disputed classification: pathogenic versus uncertain significance remains unresolved. Modifier loci and crossover suppressors can support mechanism plausibility, but they do not establish variant-specific pathogenicity or calibrate penetrance. Classification-changing evidence would require a defined human allele with cosegregation, allele-specific functional impairment, and an effect size linked to meiotic aneuploidy; pathway-level model-organism findings should remain supporting evidence only.
