Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 02, 2023The c.938C>T (p.S313L) alteration is located in exon 8 (coding exon 8) of the TMEM44 gene. This alteration results from a C to T substitution at nucleotide position 938, causing the serine (S) at amino acid position 313 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
