Genes affected

FSCN2 (HGNC:3960): (fascin actin-bundling protein 2, retinal) This gene encodes a member of the fascin protein family. Fascins crosslink actin into filamentous bundles within dynamic cell extensions. This family member is proposed to play a role in photoreceptor disk morphogenesis. A mutation in this gene results in one form of autosomal dominant retinitis pigmentosa and macular degeneration. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.010590553).
• BP6: Variant 17-81528943-C-T is Benign according to our data. Variant chr17-81528943-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 167106.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr17-81528943-C-T is described in Lovd as [Benign].
• BS2: High AC in GnomAd4 at 925 AD gene.
