Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.925T>A (p.S309T) alteration is located in exon 3 (coding exon 2) of the DMRTA2 gene. This alteration results from a T to A substitution at nucleotide position 925, causing the serine (S) at amino acid position 309 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
