Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2021The c.725C>T (p.P242L) alteration is located in exon 5 (coding exon 5) of the PHF21B gene. This alteration results from a C to T substitution at nucleotide position 725, causing the proline (P) at amino acid position 242 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
