Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.1960G>A (p.G654S) alteration is located in exon 16 (coding exon 15) of the FSTL4 gene. This alteration results from a G to A substitution at nucleotide position 1960, causing the glycine (G) at amino acid position 654 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
