Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2021The c.2913A>C (p.Q971H) alteration is located in exon 14 (coding exon 14) of the PCNX2 gene. This alteration results from a A to C substitution at nucleotide position 2913, causing the glutamine (Q) at amino acid position 971 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
