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]

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). Predicted Consequence/Location: Missense variant In silico tool predictions suggest damaging effect of the variant on gene or gene product [REVEL: 0.93 (>=0.6, sensitivity 0.68 and specificity 0.92); 3Cnet: 0.97 (>=0.6, sensitivity 0.72 and precision 0.9)]. Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000007362 /PMID: 15557452, 25324289).The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 15557452, 25324289).The variant has been reported to co-segregate with the disease in at least one similarly affected relative/individual in the same family or similarly affected unrelated family (PMID: 15557452). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

This sequence change replaces phenylalanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 382 of the TULP1 protein (p.Phe382Ser). This variant is present in population databases (rs121909076, gnomAD 0.006%). This missense change has been observed in individuals with retinitis pigmentosa and Leber congenital amaurosis (PMID: 15557452, 25324289, 32901917, 33090715, 33946315). It has also been observed to segregate with disease in related individuals. This variant is also known as p.Phe329Ser. ClinVar contains an entry for this variant (Variation ID: 7362). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt TULP1 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -
