Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.617G>A (p.G206E) 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 617, causing the glycine (G) at amino acid position 206 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
