Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.418C>T (p.L140F) alteration is located in exon 4 (coding exon 4) of the ZFYVE21 gene. This alteration results from a C to T substitution at nucleotide position 418, causing the leucine (L) at amino acid position 140 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
