Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2024The c.191A>G (p.Y64C) alteration is located in exon 3 (coding exon 2) of the PHF20 gene. This alteration results from a A to G substitution at nucleotide position 191, causing the tyrosine (Y) at amino acid position 64 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
