Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.479C>T (p.T160I) alteration is located in exon 3 (coding exon 3) of the ARHGEF38 gene. This alteration results from a C to T substitution at nucleotide position 479, causing the threonine (T) at amino acid position 160 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
