Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.157G>A (p.V53M) alteration is located in exon 2 (coding exon 2) of the CNGA4 gene. This alteration results from a G to A substitution at nucleotide position 157, causing the valine (V) at amino acid position 53 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
