The c.134C>A (p.P45H) alteration is located in exon 3 (coding exon 3) of the IGSF5 gene. This alteration results from a C to A substitution at nucleotide position 134, causing the proline (P) at amino acid position 45 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
