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.455T>G (p.F152C) alteration is located in exon 5 (coding exon 5) of the PRIM1 gene. This alteration results from a T to G substitution at nucleotide position 455, causing the phenylalanine (F) at amino acid position 152 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
