Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.2096G>A (p.R699H) 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 2096, causing the arginine (R) at amino acid position 699 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
