    A new numerical method, distorted shell clustering, accurately identifies syndromes by quantifying phenotypic resemblance. This approach correctly classifies individuals, including those with Down syndrome, improving syndrome classification efficiency.

    Area of Science:

    • Medical informatics
    • Genetics
    • Bioinformatics

    Background:

    • Syndrome classification relies on grouping individuals by shared phenotypic traits.
    • Quantifying phenotypic resemblance is crucial for accurate syndrome identification.
    • Existing methods may struggle with overlapping phenotypes and intra-syndrome variability.

    Purpose of the Study:

    • To introduce and evaluate a novel numerical method for syndrome classification.
    • To quantify phenotypic resemblance for improved syndrome identification.
    • To assess the method's ability to handle complex phenotypic data.

    Main Methods:

    • Development of the distorted shell clustering algorithm.
    • Quantification of phenotypic resemblance using numerical analysis.

  • Comparison with four other clustering methods using Down syndrome data.

    • Main Results:

    • The distorted shell method accurately classified individuals into Down and non-Down groups without error.
    • The method demonstrated high efficiency in syndrome classification.
    • It effectively accounts for overlapping phenotypes and variability within syndromes.

    Conclusions:

    • Distorted shell clustering offers a robust and accurate approach to syndrome classification.
    • This numerical method enhances the ability to identify syndromes based on phenotypic data.
    • The findings suggest potential for improved diagnostic tools in genetic disorders.
