Genes affected

RPAIN (HGNC:28641): (RPA interacting protein) Predicted to enable metal ion binding activity. Acts upstream of or within several processes, including DNA metabolic process; protein import into nucleus; and response to UV. Located in PML body; cytoplasm; and fibrillar center. [provided by Alliance of Genome Resources, Apr 2022]

C1QBP (HGNC:1243): (complement C1q binding protein) The human complement subcomponent C1q associates with C1r and C1s in order to yield the first component of the serum complement system. The protein encoded by this gene is known to bind to the globular heads of C1q molecules and inhibit C1 activation. This protein has also been identified as the p32 subunit of pre-mRNA splicing factor SF2, as well as a hyaluronic acid-binding protein. [provided by RefSeq, Jul 2008]

(HGNC:):

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.
