Genes affected

PDGFRL (HGNC:8805): (platelet derived growth factor receptor like) This gene encodes a protein with significant sequence similarity to the ligand binding domain of platelet-derived growth factor receptor beta. Mutations in this gene, or deletion of a chromosomal segment containing this gene, are associated with sporadic hepatocellular carcinomas, colorectal cancers, and non-small cell lung cancers. This suggests this gene product may function as a tumor suppressor. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0015561879).
• BP6: Variant 8-17589618-T-C is Benign according to our data. Variant chr8-17589618-T-C is described in ClinVar as [Benign]. Clinvar id is 714375.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0109 (1657/152196) while in subpopulation AFR AF= 0.0382 (1585/41524). AF 95% confidence interval is 0.0366. There are 40 homozygotes in gnomad4. There are 733 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 39 AR gene
