The c.2292G>T (p.Q764H) alteration is located in exon 8 (coding exon 8) of the FAM171A1 gene. This alteration results from a G to T substitution at nucleotide position 2292, causing the glutamine (Q) at amino acid position 764 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
