Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 23, 2021The c.850C>T (p.P284S) alteration is located in exon 4 (coding exon 4) of the PHF23 gene. This alteration results from a C to T substitution at nucleotide position 850, causing the proline (P) at amino acid position 284 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
