Genes affected

TULP1 (HGNC:12423): (TUB like protein 1) This gene encodes a member of the tubby-like gene family (TULPs). Members of this family have been identified in plants, vertebrates, and invertebrates. TULP proteins share a conserved C-terminal region of approximately 200 amino acid residues. The protein encoded by this gene is thought to play a role in the physiology of photoreceptors. Mutations in this gene are associated with recessive juvenile retinitis pigmentosa and Leber congenital amaurosis-15. [provided by RefSeq, Nov 2016]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 6-35512189-TC-T is Pathogenic according to our data. Variant chr6-35512189-TC-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 191330.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr6-35512189-TC-T is described in Lovd as [Likely_pathogenic].
