Genes affected

DDI1 (HGNC:18961): (DNA damage inducible 1 homolog 1) Predicted to enable aspartic-type endopeptidase activity. Involved in several processes, including cellular response to hydroxyurea; proteasomal protein catabolic process; and regulation of DNA stability. [provided by Alliance of Genome Resources, Apr 2022]

PDGFD (HGNC:30620): (platelet derived growth factor D) The protein encoded by this gene is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a core motif of eight cysteines, seven of which are found in this factor. This gene product only forms homodimers and, therefore, does not dimerize with the other three family members. It differs from alpha and beta members of this family in having an unusual N-terminal domain, the CUB domain. Two splice variants have been identified for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.00266549).
• BP6: Variant 11-104036945-C-T is Benign according to our data. Variant chr11-104036945-C-T is described in ClinVar as [Benign]. Clinvar id is 770220.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-3.58 with no splicing effect.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.00402 (613/152314) while in subpopulation AMR AF= 0.0336 (515/15306). AF 95% confidence interval is 0.0312. There are 19 homozygotes in gnomad4. There are 369 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 19 AR gene
