Evolutionary Relationships through Genome Comparisons

5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Summary

The Mendelian Phenotype Search Engine (MPSE) improved whole genome sequencing (WGS) use in neonatal intensive care units. This AI tool expedited WGS decisions, increasing diagnostic yield for critically ill newborns.

Area of Science:

  • Medical Informatics
  • Genomics
  • Neonatology

Background:

  • Neonatal intensive care units (NICUs) often manage complex cases requiring rapid diagnosis.
  • Whole genome sequencing (WGS) offers diagnostic potential but faces challenges in timely implementation.
  • Clinical decision support tools can aid in integrating advanced genomic technologies.

Purpose of the Study:

  • To evaluate the impact of the Mendelian Phenotype Search Engine (MPSE) on WGS utilization in NICU patients.
  • To assess changes in the time to order WGS and its diagnostic yield after MPSE implementation.

Main Methods:

  • The Mendelian Phenotype Search Engine (MPSE) is a clinical decision support tool.
  • MPSE utilizes Natural Language Processing (NLP) and Machine Learning (ML) algorithms.
  • The study assessed WGS ordering patterns and diagnostic outcomes before and after MPSE introduction.

Main Results:

  • MPSE implementation led to increased utilization of WGS in the NICU.
  • The time required to order WGS for patients decreased significantly post-MPSE.
  • The diagnostic yield of WGS in this patient population saw a notable increase.

Conclusions:

  • The MPSE effectively supports neonatologists in making timely WGS decisions.
  • AI-driven tools like MPSE can enhance the diagnostic workflow for rare genetic diseases in neonates.
  • Increased WGS use and diagnostic yield suggest improved patient care pathways through advanced technology.
