Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2022The c.1364C>T (p.A455V) alteration is located in exon 12 (coding exon 12) of the PHF21B gene. This alteration results from a C to T substitution at nucleotide position 1364, causing the alanine (A) at amino acid position 455 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
