The c.778G>A (p.A260T) alteration is located in exon 7 (coding exon 6) of the LBHD1 gene. This alteration results from a G to A substitution at nucleotide position 778, causing the alanine (A) at amino acid position 260 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
