Collection Method: clinical testing

The c.88C>A (p.L30M) alteration is located in exon 2 (coding exon 2) of the TMEM86A gene. This alteration results from a C to A substitution at nucleotide position 88, causing the leucine (L) at amino acid position 30 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
