Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2021The c.1837G>A (p.D613N) alteration is located in exon 15 (coding exon 15) of the FAM13A gene. This alteration results from a G to A substitution at nucleotide position 1837, causing the aspartic acid (D) at amino acid position 613 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
