Genes affected
LRP1B (HGNC:6693): (LDL receptor related protein 1B) This gene encodes a member of the low density lipoprotein (LDL) receptor family. These receptors play a wide variety of roles in normal cell function and development due to their interactions with multiple ligands. Disruption of this gene has been reported in several types of cancer. [provided by RefSeq, Jun 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 08, 2022The c.13049G>A (p.R4350H) alteration is located in exon 85 (coding exon 85) of the LRP1B gene. This alteration results from a G to A substitution at nucleotide position 13049, causing the arginine (R) at amino acid position 4350 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
