Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 11, 2023The c.1138G>A (p.V380I) alteration is located in exon 13 (coding exon 12) of the CHID1 gene. This alteration results from a G to A substitution at nucleotide position 1138, causing the valine (V) at amino acid position 380 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
