Genes affected

CERT1 (HGNC:2205): (ceramide transporter 1) This gene encodes a kinase that specifically phosphorylates the N-terminal region of the non-collagenous domain of the alpha 3 chain of type IV collagen, known as the Goodpasture antigen. Goodpasture disease is the result of an autoimmune response directed at this antigen. One isoform of this protein is also involved in ceramide intracellular transport. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

POLK (HGNC:9183): (DNA polymerase kappa) This gene encodes a member of the DNA polymerase type-Y family of proteins. The encoded protein is a specialized DNA polymerase that catalyzes translesion DNA synthesis, which allows DNA replication in the presence of DNA lesions. Human cell lines lacking a functional copy of this gene exhibit impaired genome integrity and enhanced susceptibility to oxidative damage. Mutations in this gene that impair enzyme activity may be associated with prostate cancer in human patients. [provided by RefSeq, Sep 2016]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0024900734).
• BP6: Variant 5-75511291-C-T is Benign according to our data. Variant chr5-75511291-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 446020.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr5-75511291-C-T is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0028 (426/152252) while in subpopulation AMR AF= 0.0217 (332/15300). AF 95% confidence interval is 0.0198. There are 9 homozygotes in gnomad4. There are 211 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 426 AD gene.
