Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2023The c.2198G>A (p.G733D) 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 2198, causing the glycine (G) at amino acid position 733 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
