Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.442C>T (p.R148W) alteration is located in exon 4 (coding exon 3) of the KIAA1644 gene. This alteration results from a C to T substitution at nucleotide position 442, causing the arginine (R) at amino acid position 148 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
