The c.1120G>T (p.V374F) alteration is located in exon 3 (coding exon 3) of the PARD6G gene. This alteration results from a G to T substitution at nucleotide position 1120, causing the valine (V) at amino acid position 374 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
