Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.300G>T (p.Q100H) alteration is located in exon 3 (coding exon 2) of the CCDC190 gene. This alteration results from a G to T substitution at nucleotide position 300, causing the glutamine (Q) at amino acid position 100 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
