The c.994A>G (p.T332A) alteration is located in exon 3 (coding exon 2) of the CCDC181 gene. This alteration results from a A to G substitution at nucleotide position 994, causing the threonine (T) at amino acid position 332 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
