• Consequence: LCA5 NM_001122769.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.27

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.0).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.787 is higher than 0.05.
