Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.818C>T (p.P273L) alteration is located in exon 6 (coding exon 6) of the PNPLA5 gene. This alteration results from a C to T substitution at nucleotide position 818, causing the proline (P) at amino acid position 273 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
