Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.2195C>T (p.S732L) 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 2195, causing the serine (S) at amino acid position 732 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
