Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2023The c.328A>G (p.T110A) alteration is located in exon 5 (coding exon 3) of the FAM193A gene. This alteration results from a A to G substitution at nucleotide position 328, causing the threonine (T) at amino acid position 110 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
