Genes affected

LRATD2 (HGNC:24166): (LRAT domain containing 2) Located in cytoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

LRATD2 links:

PCAT1 (HGNC:43022): (prostate cancer associated transcript 1) This gene produces a long non-coding RNA that promotes cell proliferation and is upregulated in prostate, colorectal, and other cancers. This RNA negatively regulates the BRCA2 tumor suppressor protein and positively regulates Myc oncoprotein. It contains binding sites for microRNAs, and may act as a sponge for microRNAs that regulate cell growth pathways. [provided by RefSeq, Dec 2017]

The c.717C>G (p.S239R) alteration is located in exon 2 (coding exon 1) of the FAM84B gene. This alteration results from a C to G substitution at nucleotide position 717, causing the serine (S) at amino acid position 239 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
