Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.6277G>A (p.E2093K) alteration is located in exon 34 (coding exon 34) of the PCNX2 gene. This alteration results from a G to A substitution at nucleotide position 6277, causing the glutamic acid (E) at amino acid position 2093 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
