The c.1030C>A (p.P344T) alteration is located in exon 3 (coding exon 3) of the ZRANB1 gene. This alteration results from a C to A substitution at nucleotide position 1030, causing the proline (P) at amino acid position 344 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
