Genes affected

LRPAP1 (HGNC:6701): (LDL receptor related protein associated protein 1) This gene encodes a protein that interacts with the low density lipoprotein (LDL) receptor-related protein and facilitates its proper folding and localization by preventing the binding of ligands. Mutations in this gene have been identified in individuals with myopia 23. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

Ambry Genetics

Dec 02, 2022

The c.638A>C (p.K213T) alteration is located in exon 5 (coding exon 5) of the LRPAP1 gene. This alteration results from a A to C substitution at nucleotide position 638, causing the lysine (K) at amino acid position 213 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
