Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2023The c.625G>T (p.A209S) alteration is located in exon 5 (coding exon 5) of the FAM173A gene. This alteration results from a G to T substitution at nucleotide position 625, causing the alanine (A) at amino acid position 209 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
