Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.325G>A (p.D109N) alteration is located in exon 3 (coding exon 3) of the GRTP1 gene. This alteration results from a G to A substitution at nucleotide position 325, causing the aspartic acid (D) at amino acid position 109 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
