Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.104T>C (p.M35T) alteration is located in exon 1 (coding exon 1) of the MRFAP1L1 gene. This alteration results from a T to C substitution at nucleotide position 104, causing the methionine (M) at amino acid position 35 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
