Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.556G>A (p.G186S) alteration is located in exon 9 (coding exon 8) of the FAM3C gene. This alteration results from a G to A substitution at nucleotide position 556, causing the glycine (G) at amino acid position 186 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
