Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 14, 2024The c.1279G>A (p.D427N) alteration is located in exon 8 (coding exon 5) of the PXYLP1 gene. This alteration results from a G to A substitution at nucleotide position 1279, causing the aspartic acid (D) at amino acid position 427 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
