Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2024The c.371C>T (p.P124L) alteration is located in exon 7 (coding exon 4) of the PXYLP1 gene. This alteration results from a C to T substitution at nucleotide position 371, causing the proline (P) at amino acid position 124 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
