Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.61C>G (p.P21A) alteration is located in exon 1 (coding exon 1) of the ZCCHC3 gene. This alteration results from a C to G substitution at nucleotide position 61, causing the proline (P) at amino acid position 21 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
