After much reading I'm still confused about the interpretation of the SugDup output column in Annovar. It seems to derive from the genomic SuperDups track at UCSC. Is this track derived from Eichler's work? Does a variant with a SegDup score mean that it is definitely in a nonfunctional pseudogene? What are the dangers of dismissing variants with SegDup scores greater than 0.9 ? Any practical advice for a hunter of Mendelian Diseases of humans?

Segmental duplication regions in the genome are hard to map to because the reads that match in that region can have multiple matches in other regions of the genome, so the variants need to be treated with caution.
Also I've heard people who do the molecular validation work on SNPs or Indels tell us that its not possible to validate anything in those regions so even if you discover something with reasonable confidence, you won't be able to design experiments to verify it.

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...04-22-2024, 07:01 AM -
Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...04-04-2024, 04:25 PM
