Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.922A>T (p.S308C) alteration is located in exon 4 (coding exon 3) of the ZSCAN23 gene. This alteration results from a A to T substitution at nucleotide position 922, causing the serine (S) at amino acid position 308 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
