The c.1261G>C (p.D421H) alteration is located in exon 2 (coding exon 2) of the HOMEZ gene. This alteration results from a G to C substitution at nucleotide position 1261, causing the aspartic acid (D) at amino acid position 421 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
