Sep 17, 2021

The c.536C>T (p.S179L) alteration is located in exon 2 (coding exon 1) of the CHD9 gene. This alteration results from a C to T substitution at nucleotide position 536, causing the serine (S) at amino acid position 179 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
