Emery-Dreifuss muscular dystrophy 5, autosomal dominant Benign:2
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

The SYNE2 p.L5386F variant was not identified in the literature but was identified in dbSNP (ID: rs184745422) and ClinVar (classified as likely benign by Invitae and as benign by Illumina). The variant was identified in control databases in 101 of 282700 chromosomes (2 homozygous) at a frequency of 0.0003573, and was observed at the highest frequency in the Latino population in 98 of 35436 chromosomes (2 homozygous) (freq: 0.002766) (Genome Aggregation Database March 6, 2019, v2.1.1). This frequency is greater than expected for the autosomal dominant Emery-Dreifuss muscular dystrophy 5 condition associated with SYNE2 variants. The p.L5386 residue is conserved in mammals and computational analyses (MUT Assesor, PolyPhen- 2, SIFT, MutationTaster, Revel, FATHMM, MetaLR, DANN) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (Splice AI exome) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
