The c.1508G>A (p.R503H) alteration is located in exon 14 (coding exon 14) of the FRMD5 gene. This alteration results from a G to A substitution at nucleotide position 1508, causing the arginine (R) at amino acid position 503 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
