The c.1108T>C (p.Y370H) alteration is located in exon 11 (coding exon 11) of the TMEM161A gene. This alteration results from a T to C substitution at nucleotide position 1108, causing the tyrosine (Y) at amino acid position 370 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
