Genes affected
SUN1 (HGNC:18587): (Sad1 and UNC84 domain containing 1) This gene is a member of the unc-84 homolog family and encodes a nuclear envelope protein with an Unc84 (SUN) domain. The protein is involved in nuclear anchorage and migration. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2019]

Emery-Dreifuss muscular dystrophy Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 16, 2023This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 5 of the SUN1 protein (p.Arg5Trp). This variant is present in population databases (rs149483651, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with SUN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 568660). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
