The c.1004G>A (p.R335Q) alteration is located in exon 3 (coding exon 3) of the TMCC3 gene. This alteration results from a G to A substitution at nucleotide position 1004, causing the arginine (R) at amino acid position 335 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
