The c.1175G>A (p.R392H) alteration is located in exon 10 (coding exon 10) of the BIN2 gene. This alteration results from a G to A substitution at nucleotide position 1175, causing the arginine (R) at amino acid position 392 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
