The c.1024G>A (p.A342T) alteration is located in exon 7 (coding exon 5) of the RHBDD3 gene. This alteration results from a G to A substitution at nucleotide position 1024, causing the alanine (A) at amino acid position 342 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
