Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 06, 2022The c.301G>A (p.G101R) alteration is located in exon 2 (coding exon 1) of the ZC3H18 gene. This alteration results from a G to A substitution at nucleotide position 301, causing the glycine (G) at amino acid position 101 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
