Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 08, 2024The c.115G>A (p.E39K) alteration is located in exon 1 (coding exon 1) of the FMR1NB gene. This alteration results from a G to A substitution at nucleotide position 115, causing the glutamic acid (E) at amino acid position 39 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
