The c.1190A>T (p.H397L) alteration is located in exon 3 (coding exon 2) of the TMEM168 gene. This alteration results from a A to T substitution at nucleotide position 1190, causing the histidine (H) at amino acid position 397 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
