The c.622C>A (p.P208T) alteration is located in exon 3 (coding exon 3) of the VGLL3 gene. This alteration results from a C to A substitution at nucleotide position 622, causing the proline (P) at amino acid position 208 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
