NM_006579.3:c.27C>G

Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 2P and 9B. PP3_ModerateBP6BS1BS2

The NM_006579.3(EBP):​c.27C>G​(p.His9Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000382 in 1,203,808 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 15 hemizygotes in GnomAD. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H9Y) has been classified as Uncertain significance.

Genes affected
EBP (HGNC:3133): (EBP cholestenol delta-isomerase) The protein encoded by this gene is an integral membrane protein of the endoplasmic reticulum. It is a high affinity binding protein for the antiischemic phenylalkylamine Ca2+ antagonist [3H]emopamil and the photoaffinity label [3H]azidopamil. It is similar to sigma receptors and may be a member of a superfamily of high affinity drug-binding proteins in the endoplasmic reticulum of different tissues. This protein shares structural features with bacterial and eukaryontic drug transporting proteins. It has four putative transmembrane segments and contains two conserved glutamate residues which may be involved in the transport of cationic amphiphilics. Another prominent feature of this protein is its high content of aromatic amino acid residues (>23%) in its transmembrane segments. These aromatic amino acid residues have been suggested to be involved in the drug transport by the P-glycoprotein. Mutations in this gene cause Chondrodysplasia punctata 2 (CDPX2; also known as Conradi-Hunermann syndrome). [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PP3
MetaRNN computational evidence supports a deleterious effect, 0.888
BP6
Variant X-48523798-C-G is Benign according to our data. Variant chrX-48523798-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 3598326.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0000559 (6/107418) while in subpopulation NFE AF = 0.0000962 (5/51998). AF 95% confidence interval is 0.0000376. There are 0 homozygotes in GnomAd4. There are 2 alleles in the male GnomAd4 subpopulation. Median coverage is 21. This position passed quality control check.
BS2
High Hemizygotes in GnomAd4 at 2 XL gene
