The c.1069T>G (p.F357V) alteration is located in exon 12 (coding exon 12) of the DENND6A gene. This alteration results from a T to G substitution at nucleotide position 1069, causing the phenylalanine (F) at amino acid position 357 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
