Genes affected

LRP12 (HGNC:31708): (LDL receptor related protein 12) This gene encodes a member of the low-density lipoprotein receptor related protein family. The product of this gene is a transmembrane protein that is differentially expressed in many cancer cells. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2010]

The c.1660G>T (p.A554S) alteration is located in exon 6 (coding exon 6) of the LRP12 gene. This alteration results from a G to T substitution at nucleotide position 1660, causing the alanine (A) at amino acid position 554 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
