not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.1072G>A (p.D358N) alteration is located in exon 10 (coding exon 8) of the FAM193A gene. This alteration results from a G to A substitution at nucleotide position 1072, causing the aspartic acid (D) at amino acid position 358 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
