Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.804G>C (p.Q268H) alteration is located in exon 4 (coding exon 3) of the ZSCAN23 gene. This alteration results from a G to C substitution at nucleotide position 804, causing the glutamine (Q) at amino acid position 268 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
