Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.3994A>G (p.T1332A) alteration is located in exon 23 (coding exon 23) of the PCNX2 gene. This alteration results from a A to G substitution at nucleotide position 3994, causing the threonine (T) at amino acid position 1332 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
