Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.1214C>T (p.P405L) alteration is located in exon 15 (coding exon 13) of the L3MBTL4 gene. This alteration results from a C to T substitution at nucleotide position 1214, causing the proline (P) at amino acid position 405 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
