Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2022The c.415G>C (p.D139H) alteration is located in exon 5 (coding exon 4) of the PHF20 gene. This alteration results from a G to C substitution at nucleotide position 415, causing the aspartic acid (D) at amino acid position 139 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
