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.1231G>A (p.G411S) alteration is located in exon 13 (coding exon 13) of the PLRG1 gene. This alteration results from a G to A substitution at nucleotide position 1231, causing the glycine (G) at amino acid position 411 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
