ClinGen Glaucoma Variant Curation Expert Panel	RCV002509613	SCV002818478	uncertain significance	Glaucoma 1, open angle, E	2022-12-14	reviewed by expert panel	curation	The c.611C>T variant in MYOC is a missense variant predicted to cause substitution of Threonine by Methionine at amino acid 204 (p.Thr204Met). The highest minor allele frequency of this variant was in the East Asian population of gnomAD (v2.1.1) = 0.0007016 (14 alleles out of 19,954), which did not meet the PM2_Supporting allele frequency threshold (<=0.0001) or the BS1 allele frequency threshold (>= 0.001). The REVEL score = 0.242, which was neither above nor below the thresholds for PP3 (>= 0.7) or BP4 (<=0.15), predicting a damaging or benign impact on MYOC function. There was no functional evidence predicting a damaging or benign impact of this variant on MYOC function. This variant has not yet been identified in a proband with juvenile or primary open angle glaucoma, only in participants of the control cohorts. Additionally, as PM2_Supporting was not met 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 primary open angle glaucoma based on the ACMG/AMP criteria met, as specified by the ClinGen Glaucoma VCEP (v1, 12 Oct 2021): none
Illumina Laboratory Services, Illumina	RCV001100399	SCV001256918	uncertain significance	Glaucoma	2018-01-15	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
