The c.1304T>C (p.I435T) alteration is located in exon 15 (coding exon 15) of the DENND6A gene. This alteration results from a T to C substitution at nucleotide position 1304, causing the isoleucine (I) at amino acid position 435 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
