# James German and the Quest to Understand Human RECQ Helicase Deficiencies

## TL;DR

This paper reviews research inspired by James German's work on Bloom syndrome to better understand related genetic disorders like Werner syndrome.

## Contribution

The paper compares Bloom syndrome with other RECQ deficiency syndromes and explores new treatment opportunities.

## Key findings

- Bloom syndrome research has influenced understanding of other RECQ deficiencies and cancer predisposition syndromes.
- Werner syndrome shares similarities with Bloom syndrome but has distinct disease mechanisms.
- New therapeutic strategies for modifying WS-associated pathways are being explored.

## Abstract

James German’s work to establish the natural history and cancer risk associated with Bloom syndrome (BS) has had a strong influence on the generation of scientists and clinicians working to understand other RECQ deficiencies and heritable cancer predisposition syndromes. I summarize work by us and others below, inspired by James German’s precedents with BS, to understand and compare BS with the other heritable RECQ deficiency syndromes with a focus on Werner syndrome (WS). What we know, unanswered questions and new opportunities are discussed, as are potential ways to treat or modify WS-associated disease mechanisms and pathways.
