The c.202A>C (p.T68P) alteration is located in exon 1 (coding exon 1) of the PLEKHG4B gene. This alteration results from a A to C substitution at nucleotide position 202, causing the threonine (T) at amino acid position 68 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
