Genes affected

LCA5 (HGNC:31923): (lebercilin LCA5) This gene encodes a protein that is thought to be involved in centrosomal or ciliary functions. Mutations in this gene cause Leber congenital amaurosis type V. Alternatively spliced transcript variants are described. [provided by RefSeq, Oct 2009]

ENSG00000231533 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 8 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 6-79487621-G-GT is Pathogenic according to our data. Variant chr6-79487621-G-GT is described in ClinVar as [Pathogenic]. Clinvar id is 967.Status of the report is no_assertion_criteria_provided, 0 stars.
