The c.947T>A (p.L316Q) alteration is located in exon 8 (coding exon 8) of the CNPPD1 gene. This alteration results from a T to A substitution at nucleotide position 947, causing the leucine (L) at amino acid position 316 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
