Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.259G>C (p.E87Q) alteration is located in exon 3 (coding exon 3) of the LRP2BP gene. This alteration results from a G to C substitution at nucleotide position 259, causing the glutamic acid (E) at amino acid position 87 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
