Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.790G>A (p.A264T) alteration is located in exon 8 (coding exon 8) of the TCEA3 gene. This alteration results from a G to A substitution at nucleotide position 790, causing the alanine (A) at amino acid position 264 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
