The c.818A>C (p.H273P) alteration is located in exon 8 (coding exon 7) of the FRMD8 gene. This alteration results from a A to C substitution at nucleotide position 818, causing the histidine (H) at amino acid position 273 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
