Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 22, 2023The c.1069G>T (p.A357S) alteration is located in exon 10 (coding exon 10) of the PHF21B gene. This alteration results from a G to T substitution at nucleotide position 1069, causing the alanine (A) at amino acid position 357 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
