The c.959A>C (p.H320P) alteration is located in exon 8 (coding exon 8) of the LRRC36 gene. This alteration results from a A to C substitution at nucleotide position 959, causing the histidine (H) at amino acid position 320 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
