Genes affected

TYRP1 (HGNC:12450): (tyrosinase related protein 1) This gene encodes a melanosomal enzyme that belongs to the tyrosinase family and plays an important role in the melanin biosynthetic pathway. Defects in this gene are the cause of rufous oculocutaneous albinism and oculocutaneous albinism type III. [provided by RefSeq, Mar 2009]

LURAP1L-AS1 (HGNC:49761): (LURAP1L antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -16 ACMG points.

• BP6: Variant 9-12709125-T-G is Benign according to our data. Variant chr9-12709125-T-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 198743.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0104 (1588/151986) while in subpopulation AFR AF = 0.0371 (1540/41492). AF 95% confidence interval is 0.0356. There are 36 homozygotes in GnomAd4. There are 731 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 36 AR gene
