ClinGen Glaucoma Variant Curation Expert Panel RCV003389741 SCV002102560 benign Open-angle glaucoma 2023-11-13 reviewed by expert panel curation The c.612G>T variant in MYOC is a synonymous variant (p.Thr204=). The highest minor allele frequency of this variant was in the African/African American population of gnomAD (v2.1.1) = 0.01075, which met the >= 0.01 threshold set for BA1 (268 alleles out of 24,932, meeting the threshold of >= 5 of at least 2,000 observed alleles). This variant was not predicted to affect splicing, as assessed with SpliceAI (<= 0.2), with a CADD score (v1.6) = 0.126 which met the <= 10 threshold for BP4, and the GERP score = -5.55 (threshold < 0), indicating a lack of conservation at this site (BP7). This evidence suggests that the variant does not impact MYOC function. A previous study (PMID: 35196929) demonstrated that the Thr204= protein had similar solubility and secretion levels to wild type myocilin protein and met the OddsPath threshold for BS3_Supporting (< 0.48), indicating that this variant did not impact protein function. Although probands with primary open angle glaucoma have been reported carrying this variant, PM2_Supporting was not met, therefore PS4 did not apply. In summary, this variant was classified as benign (BA1 is a stand-alone criterion for a benign level of pathogenicity) for primary open angle glaucoma based on the ACMG/AMP criteria met, as specified by the ClinGen Glaucoma VCEP (v1, 12 Oct 2021): BA1, BP4, BP7, BS3_Supporting

Illumina Laboratory Services, Illumina RCV001100395 SCV001256914 likely benign Glaucoma 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
Illumina Laboratory Services, Illumina RCV001100396 SCV001256915 likely benign Glaucoma 1, open angle, A 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
