Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.116C>A (p.A39D) alteration is located in exon 2 (coding exon 1) of the TROAP gene. This alteration results from a C to A substitution at nucleotide position 116, causing the alanine (A) at amino acid position 39 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
