Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.1631T>C (p.I544T) alteration is located in exon 13 (coding exon 13) of the SLC5A4 gene. This alteration results from a T to C substitution at nucleotide position 1631, causing the isoleucine (I) at amino acid position 544 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
