Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2022The c.289C>G (p.R97G) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a C to G substitution at nucleotide position 289, causing the arginine (R) at amino acid position 97 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
