Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.65G>A (p.S22N) alteration is located in exon 1 (coding exon 1) of the FSCN3 gene. This alteration results from a G to A substitution at nucleotide position 65, causing the serine (S) at amino acid position 22 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
