  • Publication number: 20230207065
    Abstract: An automated pathogenic mutation classification method is provided, which includes producing a population score using a population database based on related information. A variant type score is produced using a variation pattern prediction tool based on the related information. A clinical score is produced using the related information or a clinical database based on the related information. A functional score is produced using a functional variant hazard prediction tool based on the related information. The population score, the variant type score, the clinical score, and the functional score are summed to obtain a pathogenic score. Probability that mutation sites suffer from a corresponding disease is determined based on the pathogenic score. When the pathogenic score is higher, the probability of the mutation sites suffering from the corresponding disease is higher.

  • Patent number: 11641939
    Abstract: A slide rail assembly and a slide rail kit are provided. The slide rail assembly includes a first rail, a second rail, a blocking member, and an operating member. The blocking member is movably mounted on the second rail. When the second rail is positioned at an extending position relative to the first rail, a blocking feature of the first rail blocks the blocking member at a first state, so as to prevent the second rail from being moved from the extending position in a retracting direction. The operating member is operated to be positioned at a position that moves the blocking member from the first state to a second state, such that the blocking feature is unable to block the blocking member at the second state. The operating member is engaged with the predetermined portion of the second rail to be retained at the position.
