The c.1053C>G (p.H351Q) alteration is located in exon 10 (coding exon 10) of the PHF21B gene. This alteration results from a C to G substitution at nucleotide position 1053, causing the histidine (H) at amino acid position 351 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
