Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.779G>A (p.R260H) 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 779, causing the arginine (R) at amino acid position 260 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
