Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2023The c.353T>C (p.I118T) alteration is located in exon 4 (coding exon 3) of the SRR gene. This alteration results from a T to C substitution at nucleotide position 353, causing the isoleucine (I) at amino acid position 118 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
