Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2021The c.44C>T (p.A15V) alteration is located in exon 4 (coding exon 1) of the PXYLP1 gene. This alteration results from a C to T substitution at nucleotide position 44, causing the alanine (A) at amino acid position 15 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
