Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2023The c.158C>T (p.T53M) alteration is located in exon 5 (coding exon 2) of the PXYLP1 gene. This alteration results from a C to T substitution at nucleotide position 158, causing the threonine (T) at amino acid position 53 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
