Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2023The c.1480G>A (p.E494K) alteration is located in exon 8 (coding exon 7) of the TMEM117 gene. This alteration results from a G to A substitution at nucleotide position 1480, causing the glutamic acid (E) at amino acid position 494 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
