Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2024The c.842G>A (p.R281Q) alteration is located in exon 8 (coding exon 7) of the DMRTC2 gene. This alteration results from a G to A substitution at nucleotide position 842, causing the arginine (R) at amino acid position 281 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
