The c.905T>A (p.L302Q) alteration is located in exon 3 (coding exon 3) of the CALHM3 gene. This alteration results from a T to A substitution at nucleotide position 905, causing the leucine (L) at amino acid position 302 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
