Genes affected

LRRC3B (HGNC:28105): (leucine rich repeat containing 3B) The protein encoded by this gene is a tumor suppressor, with lowered expression levels found in gastric, renal, colorectal, lung, and breast cancer tissues. The promoter of this gene is frequently hypermethylated in these cancer tissues, although the hypermethylation does not appear to be the cause of the reduced expression of this gene. Several transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Dec 2015]

Feb 12, 2024

The c.642C>A (p.F214L) alteration is located in exon 2 (coding exon 1) of the LRRC3B gene. This alteration results from a C to A substitution at nucleotide position 642, causing the phenylalanine (F) at amino acid position 214 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
