Ambry Genetics

Sep 26, 2023

The c.230C>A (p.P77H) alteration is located in exon 1 (coding exon 1) of the LRRC37B gene. This alteration results from a C to A substitution at nucleotide position 230, causing the proline (P) at amino acid position 77 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
