Labcorp Genetics (formerly Invitae), Labcorp	RCV001054314	SCV001218623	pathogenic	not provided	2023-12-05	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Gln301*) in the TULP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TULP1 are known to be pathogenic (PMID: 8606774, 10549638, 15024725, 18055821). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with autosomal recessive inherited retinal dystrophy (PMID: 18936139, 25342276). ClinVar contains an entry for this variant (Variation ID: 828151). For these reasons, this variant has been classified as Pathogenic.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV001251337	SCV001426900	pathogenic	Leber congenital amaurosis	2020-07-02	criteria provided, single submitter	clinical testing	Variant summary: TULP1 c.901C>T (p.Gln301X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant was absent in 249232 control chromosomes (gnomAD). c.901C>T has been reported in the compound heterozygous and homozygous state in numerous patients affected with Leber congenital amaurosis, Retinitis pigmentosa or Cone dystrophy (Li_2009, Abu-Safieh_2013, Khan_2015). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two ClinVar submitters (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
