Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 02, 2024The c.821G>A (p.R274Q) alteration is located in exon 2 (coding exon 2) of the FSCN3 gene. This alteration results from a G to A substitution at nucleotide position 821, causing the arginine (R) at amino acid position 274 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
