Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.262G>A (p.E88K) alteration is located in exon 2 (coding exon 1) of the ZSCAN20 gene. This alteration results from a G to A substitution at nucleotide position 262, causing the glutamic acid (E) at amino acid position 88 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
