Gene/syndrome under study

Koolen de Vries syndrome (OMIM #610443; ORPHA: 96169); KANSL1 (OMIM *612452)

Abstract

We are seeking collaboration to advance research on Koolen de Vries syndrome (KdVS), a multisystem neurodevelopmental disorder typically caused by a 17q21.31 deletion which affects the KANSL1 gene, or by a heterozygous pathogenic variant in KANSL1. Most single nucleotide variants associated with this condition are de novo frameshift and nonsense mutations. However, we are particularly interested in patients with missense KANSL1 variants, especially those located at or near the highly conserved Arg592 codon.

Our aim is to compile detailed clinical data, assess phenotypic similarities using PhenoScore, and perform DNA methylation analysis to deepen our understanding of the mechanisms driving KdVS. If you are working with relevant cases or have patients who fit this profile, we would greatly appreciate your collaboration.
