Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.565G>C (p.G189R) alteration is located in exon 9 (coding exon 8) of the FAM3C gene. This alteration results from a G to C substitution at nucleotide position 565, causing the glycine (G) at amino acid position 189 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
