The c.671C>A (p.P224H) alteration is located in exon 5 (coding exon 5) of the RELL2 gene. This alteration results from a C to A substitution at nucleotide position 671, causing the proline (P) at amino acid position 224 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
