Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.134G>T (p.R45L) alteration is located in exon 2 (coding exon 1) of the ZSCAN21 gene. This alteration results from a G to T substitution at nucleotide position 134, causing the arginine (R) at amino acid position 45 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
