Overview

Sian Ellard is affiliated with the University of Exeter in the United Kingdom. Their research spans multiple aspects of genetics, molecular biology, and medicine, with a focus on genomic and rare diseases as well as metabolic disorders such as diabetes.

Their recent publications include works on variant pathogenicity classification, splicing impact evidence in genetic evaluation, interpretation of non-coding genomic variants, clinical diagnostic enhancement through blood RNA analysis, and updates on variants in pancreatic KATP channel genes linked to congenital hyperinsulinism and diabetes. Notable papers are:

  • Calibration of computational tools for missense variant pathogenicity classification and ClinGen recommendations for PP3/BP4 criteria (2022, The American Journal of Human Genetics)
  • Using the ACMG/AMP framework to capture evidence related to predicted and observed impact on splicing: Recommendations from the ClinGen SVI Splicing Subgroup (2023, The American Journal of Human Genetics)
  • Recommendations for clinical interpretation of variants found in non-coding regions of the genome (2022, Genome Medicine)
  • Blood RNA analysis can increase clinical diagnostic rate and resolve variants of uncertain significance (2020, Genetics in Medicine)
  • Update of variants identified in the pancreatic β-cell KATP channel genes KCNJ11 and ABCC8 in individuals with congenital hyperinsulinism and diabetes (2020, Human Mutation)

Ellard's research is frequently published in venues such as The American Journal of Human Genetics, Genetics in Medicine, bioRxiv (Cold Spring Harbor Laboratory), Yearbook of Pediatric Endocrinology, and Journal of Medical Genetics.
