Uncertain significance, criteria provided, single submitter	clinical testing	Genetic Services Laboratory, University of Chicago	Jul 09, 2019	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Nov 14, 2023	The c.1217T>A (p.L406Q) 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 1217, causing the leucine (L) at amino acid position 406 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
