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]

The c.50A>G (p.D17G) alteration is located in exon 2 (coding exon 1) of the ESCO2 gene. This alteration results from a A to G substitution at nucleotide position 50, causing the aspartic acid (D) at amino acid position 17 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 17 of the ESCO2 protein (p.Asp17Gly). This variant is present in population databases (rs141013081, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with ESCO2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0". The glycine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
