The c.564T>G (p.F188L) alteration is located in exon 4 (coding exon 4) of the CNGA4 gene. This alteration results from a T to G substitution at nucleotide position 564, causing the phenylalanine (F) at amino acid position 188 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
