Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.2180G>A (p.R727Q) alteration is located in exon 17 (coding exon 16) of the PHF20L1 gene. This alteration results from a G to A substitution at nucleotide position 2180, causing the arginine (R) at amino acid position 727 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
