The c.1304T>C (p.V435A) alteration is located in exon 14 (coding exon 14) of the FRMD5 gene. This alteration results from a T to C substitution at nucleotide position 1304, causing the valine (V) at amino acid position 435 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
