The c.1776G>C (p.Q592H) alteration is located in exon 12 (coding exon 12) of the TMEM245 gene. This alteration results from a G to C substitution at nucleotide position 1776, causing the glutamine (Q) at amino acid position 592 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
