Neurogenetic conversations need phenotype timing, variant mechanism, and uncertainty revisited.

Use three required blocks: hepatic steatosis phenotyping, external validation, and EHR missingness terms such as missing predictor, incomplete record, unavailable variable, or data sparsity. Add abstention, unclassified, assignment failure, and no prediction as a separate optional block, since requiring those terms could miss studies that report excluded or unevaluable cases without naming abstention. A recent review confirms that EHR missingness may be systematic or nonsystematic and that reporting guidance remains sparse, which supports searching several missingness labels rather than one fixed phrase.

When a kinship discrepancy changes neurogenetic segregation

SNP panels may reveal that the recorded pedigree does not match the genetic relationship used in a kinship calculation. In a neurogenetic evidence review, that discrepancy could also change which relatives count as informative for segregation and whether phenotype timing supports the proposed variant mechanism. Should the segregation analysis be repeated under each plausible pedigree, and should age at onset or current age be revisited before changing the phenotype match? The key distinction is whether the new information changes only the relationship model or also the variant interpretation.
