Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2024The c.910G>A (p.A304T) alteration is located in exon 4 (coding exon 4) of the TRABD2A gene. This alteration results from a G to A substitution at nucleotide position 910, causing the alanine (A) at amino acid position 304 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
