Genes affected

MSN (HGNC:7373): (moesin) Moesin (for membrane-organizing extension spike protein) is a member of the ERM family which includes ezrin and radixin. ERM proteins appear to function as cross-linkers between plasma membranes and actin-based cytoskeletons. Moesin is localized to filopodia and other membranous protrusions that are important for cell-cell recognition and signaling and for cell movement. [provided by RefSeq, Jul 2008]

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 23 of the MSN protein (p.Asn23Ser). This variant is present in population databases (no rsID available, gnomAD 0.02%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with MSN-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
