Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 23, 2023The c.784G>T (p.A262S) alteration is located in exon 3 (coding exon 3) of the PRR22 gene. This alteration results from a G to T substitution at nucleotide position 784, causing the alanine (A) at amino acid position 262 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
