Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.716T>C (p.L239P) alteration is located in exon 8 (coding exon 5) of the PXYLP1 gene. This alteration results from a T to C substitution at nucleotide position 716, causing the leucine (L) at amino acid position 239 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
