Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 11, 2024The c.307G>A (p.A103T) alteration is located in exon 2 (coding exon 2) of the THSD7B gene. This alteration results from a G to A substitution at nucleotide position 307, causing the alanine (A) at amino acid position 103 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
