Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2024The c.374G>A (p.R125Q) alteration is located in exon 2 (coding exon 2) of the GDE1 gene. This alteration results from a G to A substitution at nucleotide position 374, causing the arginine (R) at amino acid position 125 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
