The c.2709G>T (p.Q903H) alteration is located in exon 17 (coding exon 16) of the CCDC57 gene. This alteration results from a G to T substitution at nucleotide position 2709, causing the glutamine (Q) at amino acid position 903 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
