Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.437C>T (p.P146L) alteration is located in exon 3 (coding exon 3) of the PXDC1 gene. This alteration results from a C to T substitution at nucleotide position 437, causing the proline (P) at amino acid position 146 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
