The c.620A>G (p.Y207C) alteration is located in exon 4 (coding exon 4) of the ARL6IP6 gene. This alteration results from a A to G substitution at nucleotide position 620, causing the tyrosine (Y) at amino acid position 207 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
