Ambry Genetics

Apr 25, 2024

The c.524T>C (p.L175P) alteration is located in exon 1 (coding exon 1) of the LRRC37B gene. This alteration results from a T to C substitution at nucleotide position 524, causing the leucine (L) at amino acid position 175 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
