Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.2108G>A (p.G703D) alteration is located in exon 4 (coding exon 4) of the FAM83C gene. This alteration results from a G to A substitution at nucleotide position 2108, causing the glycine (G) at amino acid position 703 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
