The c.103G>A (p.A35T) alteration is located in exon 1 (coding exon 1) of the TMEM260 gene. This alteration results from a G to A substitution at nucleotide position 103, causing the alanine (A) at amino acid position 35 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
