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

Classification was made for transcript

Our verdict: Pathogenic. The variant received 17 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr6-35505751-C-G is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 3248791.Status of the report is no_assertion_criteria_provided, 0 stars.
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 30 curated pathogenic missense variants (we use a threshold of 10). The gene has 7 curated benign missense variants. Gene score misZ: 0.64726 (below the threshold of 3.09). Trascript score misZ: -0.4024 (below the threshold of 3.09). GenCC associations: The gene is linked to retinitis pigmentosa, retinitis pigmentosa 14, Leber congenital amaurosis 15, Leber congenital amaurosis.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.993
PP5
Variant 6-35505751-C-A is Pathogenic according to our data. Variant chr6-35505751-C-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 30262.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
