Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 21, 2021The c.320C>T (p.P107L) alteration is located in exon 6 (coding exon 3) of the PXYLP1 gene. This alteration results from a C to T substitution at nucleotide position 320, causing the proline (P) at amino acid position 107 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
