The c.377C>A (p.T126N) alteration is located in exon 4 (coding exon 4) of the PHF23 gene. This alteration results from a C to A substitution at nucleotide position 377, causing the threonine (T) at amino acid position 126 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
