Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.1334C>T (p.P445L) alteration is located in exon 14 (coding exon 14) of the MORN1 gene. This alteration results from a C to T substitution at nucleotide position 1334, causing the proline (P) at amino acid position 445 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
