Genes affected

ESCO2 (HGNC:27230): (establishment of sister chromatid cohesion N-acetyltransferase 2) This gene encodes a protein that may have acetyltransferase activity and may be required for the establishment of sister chromatid cohesion during the S phase of mitosis. Mutations in this gene have been associated with Roberts syndrome. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Dec 09, 2023	This sequence change creates a premature translational stop signal (p.Arg293Serfs*7) in the ESCO2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ESCO2 are known to be pathogenic (PMID: 15821733, 16380922). This variant is present in population databases (rs771324896, gnomAD 0.007%). This premature translational stop signal has been observed in individuals with Roberts syndrome (PMID: 15821733, 18411254, 19574259). ClinVar contains an entry for this variant (Variation ID: 21251). For these reasons, this variant has been classified as Pathogenic. -
