Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.1343C>T (p.P448L) alteration is located in exon 8 (coding exon 5) of the PXYLP1 gene. This alteration results from a C to T substitution at nucleotide position 1343, causing the proline (P) at amino acid position 448 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
