The c.3152C>A (p.T1051N) alteration is located in exon 13 (coding exon 12) of the FAM135B gene. This alteration results from a C to A substitution at nucleotide position 3152, causing the threonine (T) at amino acid position 1051 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
