The c.11G>T (p.R4M) alteration is located in exon 1 (coding exon 1) of the CCDC138 gene. This alteration results from a G to T substitution at nucleotide position 11, causing the arginine (R) at amino acid position 4 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
