not specified Uncertain:1
The c.667C>T (p.L223F) alteration is located in exon 5 (coding exon 5) of the NPAS1 gene. This alteration results from a C to T substitution at nucleotide position 667, causing the leucine (L) at amino acid position 223 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
