Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.658G>A (p.G220R) alteration is located in exon 5 (coding exon 5) of the FAM173A gene. This alteration results from a G to A substitution at nucleotide position 658, causing the glycine (G) at amino acid position 220 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
