Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.368T>A (p.V123E) alteration is located in exon 3 (coding exon 2) of the LLPH gene. This alteration results from a T to A substitution at nucleotide position 368, causing the valine (V) at amino acid position 123 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
