The c.892A>G (p.M298V) alteration is located in exon 8 (coding exon 5) of the PXYLP1 gene. This alteration results from a A to G substitution at nucleotide position 892, causing the methionine (M) at amino acid position 298 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
