Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.64A>T (p.S22C) alteration is located in exon 1 (coding exon 1) of the FSCN3 gene. This alteration results from a A to T substitution at nucleotide position 64, causing the serine (S) at amino acid position 22 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
