Genes affected
ZSCAN4 (HGNC:23709): (zinc finger and SCAN domain containing 4) The ZSCAN4 gene encodes a protein involved in telomere maintenance and with a key role in the critical feature of mouse embryonic stem (ES) cells, namely, defying cellular senescence and maintaining normal karyotype for many cell divisions in culture (Zalzman et al., 2010 [PubMed 20336070]).[supplied by OMIM, May 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2023The c.658A>G (p.I220V) alteration is located in exon 5 (coding exon 3) of the ZSCAN4 gene. This alteration results from a A to G substitution at nucleotide position 658, causing the isoleucine (I) at amino acid position 220 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
