Genes affected

PLRG1 (HGNC:9089): (pleiotropic regulator 1) This gene encodes a core component of the cell division cycle 5-like (CDC5L) complex. The CDC5L complex is part of the spliceosome and is required for pre-mRNA splicing. The encoded protein plays a critical role in alternative splice site selection. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

The c.413C>G (p.A138G) alteration is located in exon 6 (coding exon 6) of the PLRG1 gene. This alteration results from a C to G substitution at nucleotide position 413, causing the alanine (A) at amino acid position 138 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
