Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 13P and 1B. PM1PM5PP2PP5_Very_StrongBP4

The NM_000372.5(TYR):​c.650G>A​(p.Arg217Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000222 in 1,612,568 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R217W) has been classified as Pathogenic.

Genes affected
TYR (HGNC:12442): (tyrosinase) The enzyme encoded by this gene catalyzes the first 2 steps, and at least 1 subsequent step, in the conversion of tyrosine to melanin. The enzyme has both tyrosine hydroxylase and dopa oxidase catalytic activities, and requires copper for function. Mutations in this gene result in oculocutaneous albinism, and nonpathologic polymorphisms result in skin pigmentation variation. The human genome contains a pseudogene similar to the 3' half of this gene. [provided by RefSeq, Oct 2008]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 12 ACMG points.

PM1
In a hotspot region, there are 11 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_000372.5
PM5
Other missense variant is known to change same aminoacid residue: Variant chr11-89178602-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 3795.
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 116 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: -1.9514 (below the threshold of 3.09). Trascript score misZ: -0.85521 (below the threshold of 3.09). GenCC associations: The gene is linked to Waardenburg syndrome type 2, oculocutaneous albinism type 1A, oculocutaneous albinism type 1, oculocutaneous albinism type 1B, minimal pigment oculocutaneous albinism type 1, temperature-sensitive oculocutaneous albinism type 1.
PP5
Variant 11-89178603-G-A is Pathogenic according to our data. Variant chr11-89178603-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 99575.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP4
Computational evidence support a benign effect (MetaRNN=0.3665866). . Strength limited to SUPPORTING due to the PP5.
