Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.607A>G (p.N203D) alteration is located in exon 10 (coding exon 9) of the FAM3C gene. This alteration results from a A to G substitution at nucleotide position 607, causing the asparagine (N) at amino acid position 203 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
