The c.199A>G (p.T67A) alteration is located in exon 2 (coding exon 2) of the CCDC62 gene. This alteration results from a A to G substitution at nucleotide position 199, causing the threonine (T) at amino acid position 67 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
