Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.1999C>G (p.L667V) alteration is located in exon 10 (coding exon 9) of the LNX2 gene. This alteration results from a C to G substitution at nucleotide position 1999, causing the leucine (L) at amino acid position 667 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
