Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PS1PM5PP2PP3_Strong

The NM_003322.6(TULP1):c.1102G>A(p.Gly368Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,882 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely pathogenic in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G368W) has been classified as Likely pathogenic.

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 11 ACMG points.

PS1

Transcript NM_003322.6 (TULP1) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar.

PM5

Other missense variant is known to change same aminoacid residue: 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.

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, 0.987
