Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.1927G>A (p.G643R) alteration is located in exon 9 (coding exon 8) of the LNX2 gene. This alteration results from a G to A substitution at nucleotide position 1927, causing the glycine (G) at amino acid position 643 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
