Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.2470C>T (p.R824W) alteration is located in exon 16 (coding exon 15) of the FSTL4 gene. This alteration results from a C to T substitution at nucleotide position 2470, causing the arginine (R) at amino acid position 824 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
