Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.487A>T (p.I163F) alteration is located in exon 4 (coding exon 4) of the MOV10L1 gene. This alteration results from a A to T substitution at nucleotide position 487, causing the isoleucine (I) at amino acid position 163 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
