Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2021The c.272C>T (p.A91V) alteration is located in exon 4 (coding exon 2) of the FAM193A gene. This alteration results from a C to T substitution at nucleotide position 272, causing the alanine (A) at amino acid position 91 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
