Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP4_Moderate BS1 BS2

The NM_000117.3(EMD):​c.608G>A​(p.Arg203His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000112 in 1,210,488 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 40 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R203S) has been classified as Uncertain significance.

Genes affected

EMD (HGNC:3331): (emerin) Emerin is a serine-rich nuclear membrane protein and a member of the nuclear lamina-associated protein family. It mediates membrane anchorage to the cytoskeleton. Dreifuss-Emery muscular dystrophy is an X-linked inherited degenerative myopathy resulting from mutation in the emerin gene. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.13711193).
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000622 (7/112450) while in subpopulation EAS AF = 0.00139 (5/3586). AF 95% confidence interval is 0.000549. There are 0 homozygotes in GnomAd4. There are 1 alleles in the male GnomAd4 subpopulation. Median coverage is 23. This position passed quality control check.
• BS2: High Hemizygotes in GnomAdExome4 at 39 XL gene
