Genes affected
CSPG4 (HGNC:2466): (chondroitin sulfate proteoglycan 4) A human melanoma-associated chondroitin sulfate proteoglycan plays a role in stabilizing cell-substratum interactions during early events of melanoma cell spreading on endothelial basement membranes. CSPG4 represents an integral membrane chondroitin sulfate proteoglycan expressed by human malignant melanoma cells. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PM2
Variant has high frequency in the AFR(0.0608651) population. However there is too low homozygotes in high coverage region: (expected more than 2, got 0).
BP4
Computational evidence support a benign effect (MetaRNN=0.003302157).
BP6
Variant 15-75690151-G-A is Benign according to our data. Variant chr15-75690151-G-A is described in ClinVar as [Benign]. Clinvar id is 402567.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00903 (1290/142802) while in subpopulation AFR AF= 0.0313 (1065/34032). AF 95% confidence interval is 0.0297. There are 0 homozygotes in gnomad4. There are 637 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
