Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.707C>A (p.P236Q) 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 707, causing the proline (P) at amino acid position 236 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
