Unilateral loss of recql4 function in Xenopus laevis tadpoles leads to ipsilateral ablation of the forelimb, hypoplastic Meckel's cartilage, and vascular defects.

Abstract excerpt

RECQL4 encodes a RecQ helicase, one of a family of DNA unwinding enzymes with roles in DNA replication, double-strand break repair, and genomic stability. Pathogenic variants in RECQL4 are clinically associated with 3 rare autosomal recessive conditions: Rothmund-Thomson syndrome type II, Baller-Gerold syndrome, and RAPADILINO syndrome. These 3 syndromes show overlapping growth retardation, low bone density, and...
