The c.1948G>A (p.A650T) alteration is located in exon 11 (coding exon 9) of the HDX gene. This alteration results from a G to A substitution at nucleotide position 1948, causing the alanine (A) at amino acid position 650 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
