Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.2639C>T (p.P880L) alteration is located in exon 13 (coding exon 10) of the POM121C gene. This alteration results from a C to T substitution at nucleotide position 2639, causing the proline (P) at amino acid position 880 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
