Genes affected

PRIM1 (HGNC:9369): (DNA primase subunit 1) The replication of DNA in eukaryotic cells is carried out by a complex chromosomal replication apparatus, in which DNA polymerase alpha and primase are two key enzymatic components. Primase, which is a heterodimer of a small subunit and a large subunit, synthesizes small RNA primers for the Okazaki fragments made during discontinuous DNA replication. The protein encoded by this gene is the small, 49 kDa primase subunit. [provided by RefSeq, Jul 2008]

The c.629C>T (p.P210L) alteration is located in exon 6 (coding exon 6) of the PRIM1 gene. This alteration results from a C to T substitution at nucleotide position 629, causing the proline (P) at amino acid position 210 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
