Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.331C>T (p.L111F) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a C to T substitution at nucleotide position 331, causing the leucine (L) at amino acid position 111 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
