Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2023The c.2205G>C (p.K735N) alteration is located in exon 4 (coding exon 4) of the FAM83C gene. This alteration results from a G to C substitution at nucleotide position 2205, causing the lysine (K) at amino acid position 735 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
