The c.699G>T (p.Q233H) alteration is located in exon 10 (coding exon 7) of the CCDC36 gene. This alteration results from a G to T substitution at nucleotide position 699, causing the glutamine (Q) at amino acid position 233 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
