RCV003127216 | SCV003803719 | uncertain significance | Glaucoma of childhood | 2023-02-15 | reviewed by expert panel | curation | The c.1452G>A variant in MYOC is a synonymous variant (p.Lys484=). The gnomAD (v2.1.1) database had poor genotype data for this genomic position and did not represent the population from which the variant has been reported (South Asian). Thus PM2_Supporting was not applied to this variant. Although this synonymous variant was not predicted to affect splicing, as assessed with SpliceAI (<=0.2), it had a CADD score (v1.6) = 10.90, which did not meet the <=10 threshold for BP4 and a GERP score = 4.88 (threshold <0), not meeting BP7 and indicating conservation at this site. There was no functional evidence predicting a damaging or benign impact of this variant on MYOC function. Although probands with JOAG have been reported carrying this variant, PM2_Supporting was not met, therefore PS4 did not apply. In summary, this variant did not meet any criteria, receiving a score of 0 and a classification as a variant of uncertain significance (uncertain significance classification range -1 to 5) for juvenile open angle glaucoma based on the ACMG/AMP criteria met, as specified by the ClinGen Glaucoma VCEP (v1, 12 Oct 2021): none |
