Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.695C>T (p.P232L) alteration is located in exon 6 (coding exon 5) of the NDEL1 gene. This alteration results from a C to T substitution at nucleotide position 695, causing the proline (P) at amino acid position 232 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
