Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2023The c.961G>A (p.V321M) alteration is located in exon 6 (coding exon 5) of the ZSCAN20 gene. This alteration results from a G to A substitution at nucleotide position 961, causing the valine (V) at amino acid position 321 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
