Variant summary

Our verdict is Pathogenic. The variant received 19 ACMG points: 19P and 0B. PS1PM1PP2PP3_StrongPP5_Very_Strong

The NM_000372.5(TYR):c.1209G>T(p.Arg403Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000199 in 1,611,534 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Pathogenic in ClinVar. Synonymous variant affecting the same amino acid position (i.e. R403R) has been classified as Likely benign.

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 19 ACMG points.

PS1

Transcript NM_000372.5 (TYR) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar.

PM1

In a hotspot region, there are 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 7 uncertain in NM_000372.5

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.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.977

PP5

Variant 11-89284797-G-T is Pathogenic according to our data. Variant chr11-89284797-G-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 3800.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
