Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.361G>C (p.G121R) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a G to C substitution at nucleotide position 361, causing the glycine (G) at amino acid position 121 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
