The c.623C>A (p.P208H) alteration is located in exon 4 (coding exon 4) of the VPS37B gene. This alteration results from a C to A substitution at nucleotide position 623, causing the proline (P) at amino acid position 208 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
