Genes affected
RAB28 (HGNC:9768): (RAB28, member RAS oncogene family) This gene encodes a member of the Rab subfamily of Ras-related small GTPases. The encoded protein may be involved in regulating intracellular trafficking. Alternative splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 9 and X.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.37718 (below the threshold of 3.09). Trascript score misZ: -0.0076161 (below the threshold of 3.09). GenCC associations: The gene is linked to cone-rod dystrophy, cone-rod dystrophy 18, RAB28-related retinopathy.
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000815 (119/1459866) while in subpopulation MID AF = 0.00191 (11/5746). AF 95% confidence interval is 0.00107. There are 0 homozygotes in GnomAdExome4. There are 78 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
