Genes affected
B3GLCT (HGNC:20207): (beta 3-glucosyltransferase) The protein encoded by this gene is a beta-1,3-glucosyltransferase that transfers glucose to O-linked fucosylglycans on thrombospondin type-1 repeats (TSRs) of several proteins. The encoded protein is a type II membrane protein. Defects in this gene are a cause of Peters-plus syndrome (PPS).[provided by RefSeq, Mar 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0038720667).
BP6
Variant 13-31274581-G-A is Benign according to our data. Variant chr13-31274581-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 96630.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00503 (766/152316) while in subpopulation SAS AF = 0.00973 (47/4828). AF 95% confidence interval is 0.00752. There are 5 homozygotes in GnomAd4. There are 372 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 5 AR gene
