Genes affected

ALG9 (HGNC:15672): (ALG9 alpha-1,2-mannosyltransferase) This gene encodes an alpha-1,2-mannosyltransferase enzyme that functions in lipid-linked oligosaccharide assembly. Mutations in this gene result in congenital disorder of glycosylation type Il. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]

Computational evidence support a benign effect (REVEL=0.054).

BP6

Variant 11-111786460-G-A is Benign according to our data. Variant chr11-111786460-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 384997.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=0.466 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00219 (333/152154) while in subpopulation AFR AF = 0.0074 (307/41494). AF 95% confidence interval is 0.00672. There are 2 homozygotes in GnomAd4. There are 157 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 2 AR,AD gene
