Collection Method: clinical testing

The c.191T>A (p.L64H) alteration is located in exon 3 (coding exon 3) of the TMEM141 gene. This alteration results from a T to A substitution at nucleotide position 191, causing the leucine (L) at amino acid position 64 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
