Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2023The c.281C>T (p.P94L) alteration is located in exon 3 (coding exon 2) of the LLPH gene. This alteration results from a C to T substitution at nucleotide position 281, causing the proline (P) at amino acid position 94 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
