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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2022The c.179G>A (p.R60K) alteration is located in exon 2 (coding exon 1) of the LRRC3B gene. This alteration results from a G to A substitution at nucleotide position 179, causing the arginine (R) at amino acid position 60 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
