The c.122C>G (p.T41S) alteration is located in exon 2 (coding exon 1) of the FAM167A gene. This alteration results from a C to G substitution at nucleotide position 122, causing the threonine (T) at amino acid position 41 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
