Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2021The c.1430G>A (p.S477N) alteration is located in exon 14 (coding exon 13) of the FBF1 gene. This alteration results from a G to A substitution at nucleotide position 1430, causing the serine (S) at amino acid position 477 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
