Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.1606G>T (p.G536C) alteration is located in exon 3 (coding exon 2) of the FIGN gene. This alteration results from a G to T substitution at nucleotide position 1606, causing the glycine (G) at amino acid position 536 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
