Genes affected

ROM1 (HGNC:10254): (retinal outer segment membrane protein 1) This gene is a member of a photoreceptor-specific gene family and encodes an integral membrane protein found in the photoreceptor disk rim of the eye. This protein can form homodimers or can heterodimerize with another photoreceptor, retinal degeneration slow (RDS). It is essential for disk morphogenesis, and may also function as an adhesion molecule involved in the stabilization and compaction of outer segment disks or in the maintenance of the curvature of the rim. Certain defects in this gene have been associated with the degenerative eye disease retinitis pigmentosa. [provided by RefSeq, Jul 2008]

EML3 (HGNC:26666): (EMAP like 3) Predicted to enable microtubule binding activity. Involved in mitotic metaphase plate congression and regulation of mitotic spindle assembly. Located in several cellular components, including midbody; mitotic spindle microtubule; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.32).
• BP6: Variant 11-62612788-G-A is Benign according to our data. Variant chr11-62612788-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 305152.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00122 (186/151888) while in subpopulation EAS AF= 0.0237 (122/5144). AF 95% confidence interval is 0.0203. There are 1 homozygotes in gnomad4. There are 110 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.

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 and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
