Variant summary

Our verdict is Benign. Variant got -16 ACMG points: 0P and 16B. BP6_Very_Strong BS1 BS2

The NM_003005.4(SELP):​c.2018A>G​(p.Asn673Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0011 in 1,613,926 control chromosomes in the GnomAD database, including 19 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt. Synonymous variant affecting the same amino acid position (i.e. N673N) has been classified as Likely benign.

Genes affected

SELP (HGNC:10721): (selectin P) This gene encodes a 140 kDa protein that is stored in the alpha-granules of platelets and Weibel-Palade bodies of endothelial cells. This protein redistributes to the plasma membrane during platelet activation and degranulation and mediates the interaction of activated endothelial cells or platelets with leukocytes. The membrane protein is a calcium-dependent receptor that binds to sialylated forms of Lewis blood group carbohydrate antigens on neutrophils and monocytes. Alternative splice variants may occur but are not well documented. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP6: Variant 1-169596008-T-C is Benign according to our data. Variant chr1-169596008-T-C is described in ClinVar as [Benign]. Clinvar id is 782395.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00595 (906/152292) while in subpopulation AFR AF= 0.0211 (877/41560). AF 95% confidence interval is 0.0199. There are 10 homozygotes in gnomad4. There are 444 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 10 gene
