Genes affected

PRKDC (HGNC:9413): (protein kinase, DNA-activated, catalytic subunit) This gene encodes the catalytic subunit of the DNA-dependent protein kinase (DNA-PK). It functions with the Ku70/Ku80 heterodimer protein in DNA double strand break repair and recombination. The protein encoded is a member of the PI3/PI4-kinase family.[provided by RefSeq, Jul 2010]

PRKDC Gene-Disease associations (from GenCC):

• severe combined immunodeficiency due to DNA-PKcs deficiency

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE, LIMITED Submitted by: Ambry Genetics, ClinGen, Labcorp Genetics (formerly Invitae), Orphanet

ACMG classification

Our verdict: Benign. The variant received -11 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.37).
• BP6: Variant 8-47927810-G-A is Benign according to our data. Variant chr8-47927810-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 475223.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=1.62 with no splicing effect.
