Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2021The c.1757G>C (p.R586P) alteration is located in exon 15 (coding exon 15) of the FAM13A gene. This alteration results from a G to C substitution at nucleotide position 1757, causing the arginine (R) at amino acid position 586 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
