Ambry Genetics RCV004041051 SCV005008583 uncertain significance Inborn genetic diseases 2024-01-19 criteria provided, single submitter clinical testing The c.40C>T (p.R14W) alteration is located in exon 1 (coding exon 1) of the PNPT1 gene. This alteration results from a C to T substitution at nucleotide position 40, causing the arginine (R) at amino acid position 14 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
