Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2023The c.5549G>A (p.R1850H) alteration is located in exon 14 (coding exon 13) of the ZNFX1 gene. This alteration results from a G to A substitution at nucleotide position 5549, causing the arginine (R) at amino acid position 1850 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
