Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 29, 2023The c.400G>T (p.A134S) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a G to T substitution at nucleotide position 400, causing the alanine (A) at amino acid position 134 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
