Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2023The c.773C>T (p.P258L) alteration is located in exon 9 (coding exon 9) of the IQCH gene. This alteration results from a C to T substitution at nucleotide position 773, causing the proline (P) at amino acid position 258 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
